You don't know where you are, but you're not alone. All of you are stuck here together, from the uninfected survivors to the competing factions of acid creatures known as undefined. Search for the truth or invent your own. Evade the undefined masses or join in their battles. It doesn't make a difference. -Explore the ruined complex and master the art of using your environment to outwit the undefined as a survivor. -Fight against rival species and infect survivors to grow your team as an undefined. -Discover different species of undefined with unique skill sets. Kick doors down as a pink bunny, hide among traffic cones as a red lizard, battle other undefined as a bright wolf, or mix the abilities of two species together as a hybrid. -There are no secrets here. --- Game version: 2.5 All changes can be viewed in the in-game changelog.
