"You've survived State of Decay. Now it's time to move forward and tell your own story. Take on an endless campaign with twists and turns based entirely on your own choices. Build up your score in the face of an ever-escalating zombie threat, and compete with survivors around the world. Complete challenges to unlock new heroes with unique weapons and skills. The deeper you go, the tougher it gets, and every choice is yours."

Breakdown is State of Decay's first DLC, which was released on both Steam and XBLA, on 29th November 2013. It adds a new game mode, Breakdown, featuring new melee weapons, firearms, playable characters, and being an infinite sandbox mode, in which one could play the game (in theory) forever.


Our first expansion comes largely from you and your dreams. Less story, more survival. Long-term survival. More difficulty. New achievements, survivors, and weapons. We hope you have as much fun with it as we have.

In Breakdown, no storyline exists, the only goal is to survive for as long as possible. When resources become depleted, players will be given the choice to advance to the next level, using an RV which they must previously locate, repair and refuel. Only 7 people (including Lily, which is automatically on the RV and cannot be removed from it) can be taken. The currently played character is on the RV unless switched to another. The player has then the ability to pick 5 additional people, making a total of 7 surivors (played character + Lily + 5 chosen survivors). All levels are set in Trumbull Valley and all the locations are the same; however, the map reverts to unexplored, containers become unlooted and the zombies get more dangerous.

At first, players will start a new game with a random character. After completing specific challenges, they will unlock and can choose to play as hero characters, each has with their own unique abilities and starting weapons. Players can also set the difficulty when starting a new game, ranging on a scale from 1 to 10. They can only select difficulty levels up to what they have unlocked (each difficulty level can only be unlocked by completing the previous one).

Difficulty multiplierEdit

Notes: Below is untested data taken from the sandbox.xml file. (This is not up to date check Steam for the last update Difficulty ramps up till lvl 100 now)

Players that want to rank high should not stay too long on the lower levels, as the low difficulty does not justify the lack of a large difficulty multiplier. As such, getting a high score on the lower levels takes too long and makes the player uncompetitive versus those that get their score up much faster thanks to the multiplier.
