State of Decay 2 was announced at Xbox's E3 2016. The game, which introduced cooperative multiplayer, which was the first in its series. The game was released on May 22, 2018.

Gameplay
State of Decay contains elements of third person combat and simulation (building base and outposts). The player is in charge of a small group of survivors and can either follow the storyline or perform tasks that ensure their community's survival. The game world is 16 square kilometers, 8 square kilometers of which is playable.

The player can choose from several locations to build a base, then reinforce and improve it with various facilities like watch towers, gardens, sleeping quarters, kitchens, workshops, medical bays, etc. to help keep survivors safe and healthy. Part of the game is balancing the use of resources: food, medicine, ammo, and construction materials. They can be obtained by scavenging, trading with NPCs, only food can be grown at the base.

The player can interact with survivors outside of their group: trading with them, helping them or recruiting them. The game features two relationship meters, the first determines if a survivor can be recruited, and the second dictates if they can be controlled. Only one survivor can be controlled at a time, though the player can ask an AI-controlled survivor to accompany them, and in certain missions, one or more AI-controlled survivors will accompany the player.

The Storyline mode features around 150 characters, with varying facial features and clothing. Each character has a fixed set of "traits" which give them advantages or flaws (such as tire out more easily, or can improve a certain skill faster). Except for the story-related characters, most characters can be assigned to survivor groups and be recruited. Each character also has an "attitude" parameter, affected by game events (a near death experience, death of another character, or having accomplished a difficult task). These attitudes can affect their behaviors, sometimes requiring player intervention.

Zombies are the main threat in State of Decay. They respawn infinitely (unless the player establishes an outpost, which prevents spawns), are attracted to noise, and are capable of sprinting nearly as fast as the characters. The player can choose to confront them directly, use stealth to sneak past them, or divert them using items like firecrackers. In addition, there are special types of zombies, such as the animal-like "Ferals" or the tank-like "Juggernauts" that are quite dangerous in one-on-one confrontations. The game doesn't have human enemies, only zombies.

The game features over 100 different weapons, including around 30 melee weapons that can be found while scavenging (they cannot be crafted). Melee weapon and firearms are further divided into sub-categories, which have different attack animations and effects. All weapons have a durability rating, and will break when used excessively without repairs. Besides weapons, the player can find or create various consumables to improve their chances of survival, such as painkillers and pipe bombs. Besides walking, the player has access to several types of cars, each with its own characteristics like maneuverability and speed. All vehicles can be damaged and destroyed when running over zombies or hitting obstacles, although they can be repaired at the home base.

Plot
The story takes place in the fictional Trumbull Valley. The first playable character is Marcus Campbell, a store clerk. After returning from a fishing trip with his friend and a Trumbull local, Ed Jones, he finds that the world has degenerated into a zombie apocalypse. The two are soon joined by Maya Torres, a soldier. They acquire a walkie-talkie and make contact with Lily Ritter. Following her direction, they make their way to a church called the Church of the Ascension, where Lily and several other survivors have made a home base. With Ed wounded, the trio accept Lily's offer to let them stay.

As the game progresses, the survivors become aware of the United States Army's presence in Trumbull Valley, led by Sergeant Erik Tan and Captain Diane Montressor. They soon learn that the army's top priority is not to evacuate the survivors, but to contain and try to find the cause of the outbreak. The players also find the local civic leader, Judge Lawton, has barricaded the courthouse with the local law enforcement. She places citizens in her care under martial laws, planning to rebuild after the zombie incursion blows over. Finally, the players are also introduced to The Wilkersons, a group of hillbilly gun-runners who are using the apocalypse to profit and exploit other survivors.

Near the end, the courthouse falls to a zombie attack and Judge Lawton dies. Captain Montressor is evacuated, leaving behind Sergeant Tan and his men. The player, along with Tan, discovers numerous dead bodies dumped at the reservoir, explaining the cause of the, "Black Fever," that has plagued numerous survivors in Trumbull Valley. With their only water source contaminated and long term survival no longer an option, they plan to leave the valley. After raiding a zombie-infested warehouse to get explosives, the group head to the only road leading out of the valley, now blocked with a massive concrete wall.

While Tan sets up the explosives, the player holds off incoming zombies. Tan realizes the detonator has malfunctioned, and the explosives cannot be detonated from a safe distance. He volunteers to manually detonate it, claiming he's already infected. He sacrifices himself and sets off the explosives, which destroys the wall. As the smoke clears, the player sees the other side is also filled with destroyed cars and bodies, implying the apocalypse has already spread outside Trumbull Valley. The survivors leave the valley and the game ends.

Breakdown
On July 20, 2013, in conjunction with the PC development for State of Decay, Undead Labs announced an upcoming downloadable content (DLC) titled "Breakdown" for both PC and console users. The DLC adds a "Sandbox Mode", where the player leads a group of survivors in repairing an RV in order to escape the valley. The DLC allows infinite gameplay and no story line, simply allowing players to put their survival skills to the test. Breakdown adds 6 levels/tiers for players to survive in, and as players progress from one level to the next, the difficulty increases, resulting in numerous faster and stronger zombies, along with higher numbers of special zombies, forcing players to sneak their way around the map and use distractions in order to survive the higher levels. To continue on to the next level, the player needs to find the RV, which spawns in random locations throughout the map with each level. The players are only allowed to take a total of six characters (Lily included) with them to the next level. On November 15, 2013, Undead Labs officially announced the Breakdown release date for November 29, 2013.

Lifeline
Not long after the release of Breakdown, Undead Labs announced that a second DLC was in development. On February 4, 2014, an addition on the Steam Database confirmed the DLC to be named "Lifeline." On February 11, 2014, Undead Labs officially announced news of the "Lifeline" DLC, also confirming it to include the fictional city of Danforth that can be seen just outside Fairfield. On February 27, it was explained that the DLC will explore the military's side during the first days of the outbreak.

The player will play the role of a military unit by the name of Greyhound One in Danforth City. The player will be tasked with keeping a group of survivors alive long enough to get them to safety, as well as defending the main base by setting traps and planning tactics. But unlike the typical survival only bases that deal with just excesses of hordes, there is a new threat called raids that get progressively harder with each one that passes. The DLC is set on more of a time-based approach instead of the never-ending approach seen in the Breakdown DLC. At the Pax East 2014 convention, Undead Labs expected it to be released on June 6, 2014. The release date was revealed to be Friday, May 30, earlier than was previously expected. The DLC features a new map and narrative. The DLC has been priced the same as the first DLC, Breakdown, which is $6.99 / £5.59.

Development
State of Decay was first announced in 2011 as an Xbox Live Arcade exclusive title originally titled Class 3. Jeff Strain, the founder of ArenaNet and co-creator of World of Warcraft, wanted a game where individual players could make up their own zombie survival plans and put them to the test. Then, he set out to create the game, which runs on CryEngine 3. On May 16, 2013, Undead Labs announced that State of Decay had gone into the final certification process and is now ready for testing by the game's publisher, Microsoft Studios. State of Decay was envisioned as a step towards Undead Labs' full online console game, Class4. Class4 will be one of the first zombie massively multiplayer online games (MMOs) to come to the Xbox One. In a 2014 interview, Undead Labs founder Jeff Strain stated that State of Decay had officially become a franchise, with the company's partnership with Microsoft Studios confirmed. He stated that the first State of Decay was "just the start of (Undead Labs') long-term ambitions".

Reception
State of Decay has received positive reviews from critics. Sanya of Undead Labs stated that "2013 Was a Damned Good Year" in terms of the positive reviews the game received. Metacritic scores range from 60/100 to 100/100, with an average score of 78/100. The game sold more than 250,000 copies in its first 48 hours of release to the Xbox Live Arcade. As of June 17, 2013, the game has sold more than 550,000 copies. Within the end of June the game had sold more than 700,000 copies, making it the second-fastest-selling XBLA game of all time. On October 4, 2013 Undead Labs announced that the game had sold one million copies. The figure combined both XBLA and Steam Early Access sales. On November 30, Undead Labs had sold more than one million copies of State of Decay.

Polygon gave a positive review, praising the survival and role-playing aspects of the game. Reviewer Arthur Gies wrote, "State of Decay is one of the most cohesive, terrifying and engaging open-world games I've ever played."

The Australian Classification Board refused classification because "[the game] contains the option of self-administered drugs throughout, in order to restore players' health or boost their stamina". Jeff Strain said "we are going to come up with options, including changing names of certain medications in the game to comply with ratings requirements. Whatever our path forward, it's going to take a bit." On July 11, 2013 State of Decay was rated R18+ for high impact violence.

Sequel
A sequel, State of Decay 2 was announced live at Xbox's 2016 E3 live conference. The game was released on May 22, 2018.
