You are at the centre of a war against the Ridden. These once-human hosts of a deadly parasite have turned into terrifying creatures bent on devouring what remains of civilization. With humanity's extinction on the line, it's up to you and your friends to take the fight to the enemy, eradicate the Ridden, and reclaim the world. Fight your way through a dynamic, perilous world in a 4-player co-op story campaign where you must work together to survive increasingly challenging missions. Play with up to 3 of your friends online or go solo and lead your team in battle. Play with or against friends in PvP mode. Become a Cleaner with special perks or switch sides and play as the horrific Ridden. Both sides come with unique weapons, abilities, and specialties. A new rogue-lite Card System creates different experiences each and every time, putting you in control to craft custom builds and undertake more demanding fights.
