Sunset Overdrive

Sunset Overdrive is an action-adventure third-person shooter video game developed by Insomniac Games and published by Microsoft Studios for the Xbox One. It was announced at Electronic Entertainment Expo 2013, and released worldwide in October 2014. The game is set in 2027, in a fictional metropolis called Sunset City. The player controls an employee of FizzCo, who has to fight off the OD, short for Overcharge Drinkers: humans who have turned into mutants after drinking FizzCo's energy drink beverage. In the dystopian Sunset City the player character can wall-run, use zip-lines, and grind rails to swiftly navigate through it, with a large arsenal of weapons to use. The game also has a cooperative multiplayer mode called Chaos Squad, which tasks players to complete a series of missions with seven players. As the game puts emphasis on momentum, the game does not feature any cover system.

The development of the game began in 2010 when Insomniac completed Resistance 3. After the project was green-lit internally, the studio partnered with Microsoft Studios, which helped fund the game and allowed Insomniac to keep the rights to the franchise. Insomniac described the game as a "celebration of games", as the team took inspiration from different sources, including Prince of Persia, Jet Set Radio and Tony Hawk's Pro Skater, though at its early stage of development the team took inspirations from DayZ instead. The game is set in a post-apocalyptic future, but the team depicted it as an "awesomepocalypse" that turns the game's initial world depiction into a "playground" for players. Sunset Overdrive is powered by Insomniac's internal engine, previously used in Fuse, one of their previous games.

The game received generally positive reviews, with praise for its visuals, traversal system, combat system, and humor. However, the game was criticized for the lack of a compelling story or innovative quest design. It received numerous nominations, including Best Xbox Game of the Year awards from several gaming publications. The game was supported with multiple downloadable content, including the story-based The Mystery of the Mooil Rig and Dawn of the Rise of the Fallen Machine, after the game's release.

Gameplay
Sunset Overdrive is an action-adventure game set in a third-person perspective. Players navigate a metropolis called Sunset City in the year 2027. This dystopian world has been overrun by mutants called the OD, short for Overcharge Drinkers. The player character is a former FizzCo employee, tasked with cleaning up the mess left behind from a party FizzCo had thrown to celebrate the launch of its new energy drink, Overcharge Delirium XT.

At the start of the game, players can customize the protagonist's gender, body type, hairstyle, and outfit using the character creator. Players may also alter the look of their customized character at any point during the game by approaching a vendor named Callista. After creating their characters, players proceed to the game's open world, which is free for players to explore at any time. A fast travel system is provided allowing players to reach different locations and to navigate the world quickly. The game features a main campaign with story elements and side-missions, which are triggered automatically when players enter certain locations in the city. These quests mainly involve players delivering objects to other non-playable characters and collecting items from the world. Some of these quests have time limits.

Throughout the game, players encounter both human enemies, such as gang members, FizzCo's robots, OD'd humans who have mutated from drinking too much of the energy drink, and several bosses who are more difficult to defeat compared with other ordinary enemies. The game features a variety of weapons for players to use to combat enemies. These include the standard assault rifle AK-FU and the TNTeddy grenade launcher, which fires teddy bears strapped to sticks of dynamite, fireworks and toy helicopters. All weapons eventually run out of ammunition but do not need to be reloaded while being used. Players unlock more weapons by progressing through the story or purchasing them from shops. Weapons can be upgraded and modified by applying "Amps", which increases weapons' lethality, efficiency, and strength. The weapons can be leveled up when players earn enough experience points or defeat enough enemies with them.

The game's combat focuses on velocity, and encourages players to defeat enemies in a fast-paced way. As a result, players can employ different moves including wall running, air-dashing, zip lining, performing parkour, acrobatics, and water traversal. Players use grind rails to deftly navigate city streets, and are able to switch direction instantly at will. The city is also filled with items for players to bounce up into the air. Players may utilize their weapons while performing these movements and slow down time for players to take aim. On-foot, players cannot walk, take cover, or take out enemies silently, but instead must rely on agility to survive as they will be overwhelmed quickly by enemies if they choose to walk on the ground. The game also features a Style Meter. Shown in the head-up display (HUD) of the game, the Meter increases as players perform stylish moves like killing enemies and grinding on-rails without touching the ground. When players are killed, they do not have to wait for the game to load. Players can respawn and return to the world by different methods, such as descending with a rocket or exiting a golden sarcophagus. Insomniac named this system "Next-Gen Respawning".

The game features an eight-player co-operative multiplayer mode called the Chaos Squad, which tasks players to complete a series of missions, as decided by the players themselves. Players defend vats of Overcharge Delirium XT from waves of OD'd at night and stop their progression by setting up fortifications and barriers, in a manner similar to tower defense games. It is inter-connected with the single-player mode allowing players to transfer their story character, with all the weapons and gadgets they have already accumulated, to the mode. Although players work together, players also try to earn more Style points during play than their co-op partners.

Plot
On July 13, 2027, FizzCo releases its new energy drink, OverCharge Delirium XT (also known as OCD), exclusively in Sunset City. In an attempt to sell OCD faster, FizzCo skipped health regulation protocols, in turn causing anyone who drinks it to turn into a violent boil-bodied mutant known as an Overcharge Drinker (OD). In order to cover up the deception, FizzCo claims that a viral outbreak has happened and quarantines the whole city, preventing anyone from entering or exiting. The player, a FizzCo employee who works in the sanitation division, is saved from an attacking OD by Walter, a fellow survivor; the player is unaffected by the drink, as they were not allowed to attend the launch party for OCD, later referred to as "Horror Night".

Upon learning that Walter is creating a plane to escape the quarantine, the player obtains the aid of Sam and the Oxfords, a group of rich but lazy geniuses. After multiple errands, the Oxfords build a propeller to complete the plane. The player joins Walter in his plane to escape the city and reveal the truth about the outbreak. At the last second, Walter notices an invisible wall preventing their escape and pushes the player out of the plane before dying in the subsequent crash.

Still planning to escape, the player aids Troop Bushido, scouts living in a samurai museum, and the Fargarths, a group of larpers. In thanks, the two groups design and build a ship out of garbage which tricks the FizzCo sensors and allow them past. As the player is about to escape, they learn that FizzCo robots are attacking the Oxfords and Troop Bushido in order to kill all witnesses. The player returns to Sunset City and rescues the survivors. Sam informs the player that there is a deadly superweapon in FizzCo headquarters, which the player is able to break into after obtaining the help of Las Catrinas, a trio of skeleton-themed Mexican American cheerleaders caring for the children's ward of a hospital, by recruiting a band fronted by King Buzzo (voiced and mocapped by the real Melvins singer) to perform for the children.

The player rallies the four factions to attack FizzCo headquarters, and attempts to destroy FizzCo HQ by riding a giant bottle of OCD into it (reminiscent of Dr. Strangelove). The player is killed in the blast, and the factions mourn them. However, the player stops the credits rolling after this scene to complain how depressing the ending is, and decides to change it. The player survives in this ending, and it is revealed that the FizzCo building is a robot that is meant to destroy the city to cover up the OCD outbreak. The player destroys the robot and has milk and crackers with the other survivors. After the credits, however, computers in the FizzCo headquarters automatically activate a protocol sending FizzCo helicopters full of OCD around the world.

Origin
Sunset Overdrive was developed by Insomniac Games, which had mainly developed games for PlayStation consoles. Drew Murray and Marcus Smith, the game's creative directors, began brainstorming Sunset Overdrive after the completion of Resistance 3 in 2011. They presented their ideas to Insomniac's owners and CEO Ted Price, outlining a project that would borrow influences from the documentary Hyena Men of Kenya, Tank Girl comics, the novel I Am Legend, the British television series The Young Ones, Halloween masks from the 1960s, and Lego. The initial presentation failed to generate interest, but Murray and Smith were asked to come back a week later to explain how the game would actually be played. In their second presentation, they explained their vision of a game featuring fast-paced action that would be "the rock and roll end times". According to Smith this confused some team members who thought that they were making Brütal Legend.

The team received approval after their second presentation. After Sunset Overdrive was green-lit internally, Insomniac had to pitch it to a number of publishers. Insomniac wanted to retain brand ownership, causing some firms to opt out of publishing it. Murray and Smith traveled to Microsoft Studios a number of times to pitch the game to them. The main pitch began with the playing of "Kick Out the Jams" by MC5, and ended with Murray: "...on top of a chair, mimicking how the game was going to play, and the last minute heroics." Microsoft was eager to work with Insomniac and agreed to fund and publish the game. The team originally did not want to make it a console exclusive, but they were impressed by Microsoft's philosophy toward the development of Xbox One, and the capabilities of Xbox Live features, which allow the initiation of a "two-way dialogue" with players.

Design
Choosing a name for the game was the first thing the team did before starting development. They decided on the name Sunset Overdrive because they felt it was unique, and captured the feeling of the "grindhouse" from the 1970s. The project was originally conceived as an open world survival game similar to DayZ. The initial version of the game did not feature the traversal system, nor the unusual weapons included in the final version, and was described as "grounded" by Murray. In this version, players were tasked with scavenging resources during daytime, and defending their base at night. This later evolved to become the game's cooperative multiplayer mode. It employed the animation model from Insomniac's previous game, Fuse. The direction of the game changed after the team watched a video based on Gorillaz, and Murray gave up the idea of a realistic survival game. He then asked the team to start prototyping ideas for a game that they thought would work. Some team members came up with the idea of having skateboarding elements in the game, which led the development team to start working and experimenting with a new traversal system. In hindsight, Murray described the shift in focus as an "organic, evolutionary process". As the game's development progressed, the team began to draw on elements from other video game franchises such as Prince of Persia, Jet Set Radio, and Tony Hawk's Pro Skater, and put the emphasis on momentum.

In 2013, the team had released Fuse, which was a critical and commercial failure. The team now reflected on the reasons for its poor reception, and felt that they should go back to Insomniac's roots — developing unusual titles with vibrant visuals — instead of another dark shooter like Fuse. They also thought that Sunset Overdrive's stylization should reflect the personality of the company, and that building a world that has a sense of humor and irreverence was something the team was eager to do. Ted Price, CEO of Insomniac Games, described it as a game Insomniac had wanted to develop for a long time. The game's producer, Bryan Intihar, called it: "...the game [they've] been meaning to make for 20 years." Microsoft supported it and shared the same vision and the idea of creating something new.

According to Price, Insomniac wanted to "break the rules of shooters". He felt that the last generation of shooters had established a formula of staying behind cover for defense, and leaning out from it to attack. He wanted to change that pattern with Sunset Overdrive by encouraging players to attack in an aggressive manner and to focus on momentum. To accomplish this, the team developed a city that supported parkour and fast movements. They also hoped that with the introduction of a new generation of video game consoles, they could establish a new standard for the genre which would "retrain" shooter fans playing the game.

Smith compared Sunset Overdrive's gameplay to pinball games, where a player's every movement has consequences, and the on-screen chaos created by players is based on their actions. The game's combat and traversal elements were originally separate from each other, but were later connected as the team began to think that: "shooting while grinding was fun". The combination of these aspects led the studio to adjust the game's world design. The team calculated how the city should be designed so that it could support both combat and traversal. As a result, they ensured that the world was built in modular 4x4 blocks, and that no surface featured an angle that was between 26 and 45 degrees. Furthermore, the team considered how long grinds should be, and decided that they should be at least 8 meters in length. The grinds were designed to be longer than usual in enemy-concentrated areas so as to allow additional time for players to consider both combat and traversal options. In order to encourage experimentation, the game features a vertical map-design, in which the difficulty the enemies' players face increases as they move towards higher ground.

Insomniac described the game as "a celebration of games", in which the team pushed existing concepts in a new direction. Besides drawing influences from Prince of Persia, Tony Hawk's Pro Skater and Jet Set Radio series of games for the game's traversal system, they drew influences from Bill & Ted's Excellent Adventure for their "Next-Gen Respawn" system, Scott Pilgrim and The Omega Man for the game's setting, and Peggle when they were creating the game's weaponry. The game's humor was inspired by Insomniac's own game series Ratchet & Clank and Spyro the Dragon. There are also references to other pop culture icons such as Breaking Bad and Portal. Despite that, Smith said that the game would be completely different from The Last of Us.

The game's character creator function allowed players to create different kinds of combinations in an avatar. The team ensured that there were many customization options, including allowing players to "dress like a crazy person". The developers felt that this feature would suit the story, because the game's city enters a state of anarchy, where social norms no longer exist. The team wanted the character creator to feature diversity, so that players could build an avatar based on their own choices. They found the process of introducing diversity challenging. As a result, a system was developed that broke the character creator down into three different categories: mainstream, street (emo and goth), and costume. The team originally added role-playing games-styled stats to the game's costumes, but later decided to scrap that so that players "would just choose what they thought looked cool."

Art and setting
The game is set in a near-future, post-apocalyptic world. The team wanted to try something different, unwilling to return to a setting that was similar to Resistance 3. Instead of depicting a world with a dark atmosphere and gritty environments, the catastrophe that occurs in the game's story line is referred to as an "awesomepocalypse” that transforms the user's initial view of the game's world as a "playground" for players to explore and do whatever they want – "emphasizing the fun of free reign [sic] during end times." The goal was to make players feel that the post-apocalyptic world in Sunset Overdrive is fun and limitless, delighting and lively, instead of a place that is dreadful and worrying. To achieve this, vibrant and vivid colors were used to create the game's world and the team hoped that by tweaking the nature of the setting, the game would be "self-aware, humorous, and fun". The team also intentionally avoided creating a very serious tone because the final product needed to be entertaining and comparable to games like Crazy Taxi and Jet Grind Radio, instead of something too serious that looked like an interactive movie. The team emphasized "fun trumps realism" and reflected that through the "Next-gen Respawn" system, unrealistic weaponry, and the game's visual style.

While the game features colorful graphics that appeal to a broad audience, it was intended for a mature audience which is reflected in the game's story, dialogue, and characters' portrayals. The story was designed to be casual, but compelling. The game's setting is inspired by both I Am Legend and imagining Iggy Pop as the last person surviving in a post-apocalyptic world. The team also wanted to create a satirical story, and explore the theme of anti-corporatism. The punk rock style was implemented in the game because the game's directors thought that it reflected a sense of "aggression", which suited the gameplay.

When designing the cover art, the team collaborated with the English studio Ilovedust. They wanted it to be easily recognized and stand out from the cover art of other video games in stores. They also wanted it to represent the game's characteristics: "intensity", "fun in the end times" in a "dynamic and vibrant world". There were three different iterations of the cover art, with major changes made to the game's protagonist throughout its development, as the studio struggled with the protagonist's portrayal. Insomniac was ultimately satisfied with Ilovedust's finished art design.

Technology
Price called Sunset Overdrive the biggest game the studio had worked on. As it was the first open world game developed by Insomniac they had to deploy new design and development skills to produce it. The time and resources needed to develop the game also expanded significantly. While developing the game's world, the team broke it down into 10 to 11 hexes and zones. They are classified into three different types: low resolution zones, shadow zones, and mission zones, and they overlap each other so that they can keep all zones loaded at the same time. Sunset City had three different iterations. In the early stages, it was called Greenlight City, based on Burbank, California. This version of the city featured interior structures that could be explored by players, and existed when the game's core concept revolved around "scavenge, craft, defend". This city was replaced with "Razor City" when skateboarding, which later became oil slicks and trampolines, was introduced to the game. Razor City was "Neo-Tokyo"-styled, but was later replaced by Sunset City which was more organized. While designing the game's artificial intelligence, the team thought that the game's enemies must force players to use the traversal system while simultaneously engaging in combat with them. Because of the game's vertical design, the enemies were designed to adopt the game's vertical map-design. The team also developed a “nav position tracker”, which programmed these enemies to detect the location of players and find an ambush point.

The game is powered by an internal engine developed previously by Insomniac Games for its game Fuse. The engine of the game was reworked and optimized for the Xbox One. The game runs on 900p at 30 frame rate per second. The game originally ran at a higher definition of 1080p, but it was decided to fix it at 900p so that more actions and enemies can appear on-screen.

Audio
Development of the game's music was led by Boris Salchow, who had composed scores for Insomniac's previous games Ratchet & Clank: A Crack In Time, Resistance 2 and Resistance 3. He collaborated with composers from Microsoft Studios, and Pyramind music studio. The design team wanted the composers to implement eight different styles of music for eight different sections featured in the game. However, this idea was dropped as being confusing and overly-chaotic. The team wanted to achieve a "high energy vibe" for this title and the resulting soundtrack features a lot of punk rock and electronic dance music. Fourteen different bands and artists were hired to perform the music often avoiding using musical instruments and writing lyrics for the game instead. The game's soundtrack was also inspired by works from FIDLAR, DZ Deathrays and Ty Segall.

Composers tried to match beats-per-minute to the gameplay and traversal system. The game features a dynamic music system, in which in-game actions are reflected by the music. When there is more on-screen action, or when players perform kills, the music becomes more frantic and exciting to help players further immerse themselves in the game.

Release
Sunset Overdrive was among one of the first Xbox One exclusives revealed at Microsoft's press conference at E3 2013. The first gameplay details were revealed by gaming magazine Edge in May 2014. A gameplay demo and a release date announcement happened at E3 2014. Insomniac had worked solely for the PlayStation family for about twenty years, and the announcement of Sunset Overdrive being an Xbox exclusive led to speculation that the relationship between Sony and Insomniac had ended. Insomniac denied such rumors, saying the company would still be working with other publishers to produce titles and that petitions would not change Sunset Overdrive's status as an Xbox exclusive. It was released on October 28, 2014.

In addition to the game's standard edition, players can purchase the game's Season Pass, which adds new in-game items, locations, quests, and bosses. There is also a Day One Edition, which includes three different downloadable content items: "Nothin' but the Hits" gun, the Hardcore Hammer, and a Fizzie costume. Players who pre-ordered the game from Xbox Live Marketplace also got two additional weapons: the Accordes de la Muerte and the Hangover. A white Xbox One bundle was also released for the game. To promote the game, Insomniac organized a series of shows called the Sunset TV. They provided new information to players regarding the game prior to its release. Microsoft also launched a website called Sunset Overdrive: Walter's Workshop, which is a browser game that allows players to use some of the weapons featured in the game with footage captured in real-life.

A three-hour free trial of the game was available for players to download for a limited time. Once it was launched the game was supported with downloadable content (DLC). Insomniac released multiple packs which add new weapons to the game. A story-based DLC, titled The Mystery of the Mooil Rig, was released on December 23, 2014. Another story DLC, Dawn of the Rise of the Fallen Machine, was released on April 1, 2015.

Critical reception
Sunset Overdrive received positive reviews. It received aggregated scores of 83% from GameRankings based on 63 reviews and 81/100 from Metacritic based on 89 reviews.

The game's tone was praised by reviewers. Daniel Bischoff from Game Revolution praised the game's comedic elements describing them as "contemporary". He added that the game is one of the rare few that made him laugh while playing. Sam Prell from Joystiq appreciated the humor, and thought that its quality was boosted by the performance of the voice-actors. His opinion was echoed by Peter Brown from GameSpot, who found the voice acting in the game entertaining and believable. However, Prell considered some humorous moments "hit-or-miss". Andrew Reiner from Game Informer described the game as a "full circle", in which Insomniac has incorporated all the elements from their previous game into this one. As a result, he thought that while the story emphasized comedy, it successfully reflected some pressing issues existing in society. Mollie L Patterson from Electronic Gaming Monthly appreciated the game's humor, but noted that it would not be able to satisfy every type of player. Arthur Gies from Polygon described the story as "gleefully stupid", and commended the self-aware narrative. Chris Carter from Destructoid praised the jokes featured in the game. However, he disliked the story, which he thought failed to offer motivation for players to complete the game.

Sunset Overdrive's gameplay was also commended by many reviewers. Prell compared the game favorably to Jet Grind Radio, Saints Row The Third, Infamous, and Ratchet & Clank. He singled out the traversal system, which he thought was fluid and well-executed. He added that the fast travel system was not useful in this game, since players can find a lot of fun by simply traveling between different locations in the game's world. He thought that all of the game's systems intertwined with each other, and ultimately made the game a complete and worthwhile experience. Reiner echoed similar thoughts, and considered getting around Sunset City fun for players. He added that the traversal system increased the game's replay value. However, he was disappointed by the game's occasionally repetitive mission design. Sliva and Brown shared similar thoughts, with the latter saying that the game featured too many fetch quests. Patterson disliked the game's traversal; he found that the system was frustrating at times. However, he thought that this problem lessened as players unlocked new moves and skills. Gies felt overwhelmed by the traversal options. He added that Insomniac had successfully created a system that was accessible for ordinary players, while creating challenges for those who want to master the system. However, he noted the camera system may not able to track the movement of the character accurately. He further commended the game's world design, and described it as one of the most "navigationally sophisticated" worlds he had ever experienced in a game. Bischoff considered the shooting mechanic "loose", but thought that the problem was overshadowed by the game's forgiving aiming and steady difficulty curve. Lucas Sullivan also criticized the mechanic, calling it "inconsistent".

The customization options received acclaim. Bischoff praised the arsenal of weapons featured in the game, which he thought was deep, interesting, and creative, benefited by the Amps system, which added additional complexity to them. Prell described it as the "king" of the game. He praised the game's ability to allow players to customize their characters, and considered the weapons featured "varied", and thought they enhanced the game with personality. Reiner thought that all of the weapons featured in the game were fun to use, and that the amps system made experimenting with different weapons rewarding. Patterson also commended the game's weapons though he was initially skeptical about them. Gies thought that the customization options allowed players to play the game as they preferred, and described the character creator as "flexible". Marty Sliva from IGN praised the Amp upgrade system, which he felt encouraged players to try out unusual ways to experiment with it.

The game's art style was applauded. Bischoff praised the colorful graphics and the different graphical effects featured in the game. He further praised the game's presentation, which he thought would lead "the Xbox One console’s personality this generation." Reiner compared the colorful graphics of the game to Sesame Street, and thought the bright colors "[electrified] the screen". Reiner also praised the "Next-Gen Respawn" system, and the protagonist's animation. Sliva praised the design of the city, as he thought it featured a unique artistic style, and aided the traversal system. He added that the game's visuals "pop", and compared them to the "Easter Bunny on an acid trip". Carter praised the variety existing within the game's world, which he considered has prevented the game's world from being repetitive, and made landmarks easily recognizable. Brown thought that the game did not look realistic, but felt this did not stop the game from being one of the best-looking games available for the console. Sullivan also praised the use of colors, which he found was organic and vibrant.

The game's multiplayer received mixed reviews. Prell thought that the mission-design was varied, and the voting system kept the mode from being repetitive. He also praised the interconnected structure between the single-player and multiplayer, noting that the items that could be carried over from multiplayer to campaign made the mode feel rewarding for players. Reiner thought that the action featured in this mode is satisfying, but thought that the system lacked enough depth and complexity to engage players. Patterson echoed similar thoughts, and felt that the ability of players to switch between the campaign and the Chaos Squad mode made the multiplayer mode a rewarding experience. Brown criticized the mode, saying that its difficulty was not properly scaled.

The game was the second best-selling game in the UK on its release, and was outsold by FIFA 15. In its second week of release, it was the eighth best-selling game.
