In a world overrun by the Ridden—people transformed by a parasite—you play as a Cleaner, an immune survivor fighting to protect what remains of humanity. The story campaign follows the Cleaners through a series of dangerous missions.
Fight through infested areas, complete objectives, and reach safety while dealing with ordinary infected, mutated enemies, and bosses. The campaign supports up to four players online or solo with AI teammates; a separate PvP mode lets players compete as Cleaners or Ridden.
Choose a Cleaner with distinct abilities, then shape a playstyle with a custom card deck and weapons fitted with attachments. Random mission modifiers change conditions from run to run, while earned cards and other progression let you develop different builds.
Players who enjoy the game often point to its gunplay and the fun of fighting through missions with friends. Many appreciate experimenting with card decks, team roles, and weapon setups, and some say changing modifiers make repeat runs feel different. Others find the card and progression systems overly complicated, and reviews also criticize difficulty balance, AI teammates, or sparse matchmaking. Comparisons with Left 4 Dead are a recurring source of disappointment, while some players say the game works better when judged on its own terms.
