You find yourself at the center of a war against the Infected. These once-human hosts of a deadly parasite have transformed into terrifying creatures bent on devouring the remnants of civilization. With the extinction of humanity at stake, it's up to you and your friends to take the fight to the enemy, eradicate the infected and take back the world.
Cooperative Campaign: Battle your way through a dynamic, dangerous world in a 4-player co-op story campaign where you must work together to survive increasingly challenging missions. Play online with up to 3 of your friends or go it alone and lead your team into battle.
Choose from 8 customizable cleaners, one of the immune survivors, and an array of deadly weapons and items. Take strategic action against an ever-evolving enemy bent on your total destruction.
Competitive multiplayer: play with or against friends in PvP mode. Switch between playing as a Cleaner with special advantages or as one of the fearsome Infected. Both sides choose from unique weapons, abilities and special skills.
High replay value: a new "rogue-lite" map system creates different experiences every time, giving you control to craft custom decks and builds and take on more challenging battles.
The game director constantly adapts to player actions for exciting battles, extreme gameplay variety, and tougher legions of infected - including mutated boss enemies up to 20 feet tall.
