Most played chaotic co-op games
Squad chaos is the common thread across these most played chaotic co-op picks, where you and friends juggle stray shots, awkward objects and plans that collapse fast. In HELLDIVERS™ 2 you call in support and scramble to leave together, while R.E.P.O. has you dragging bulky salvage past creatures, and Chained Together links every jump to the whole group. Expect shouting, laughter and rescues that barely work.
