Left 4 Dead 2

Left 4 Dead 2 is a co-operative first-person zombie shooter by Valve. Teams of survivors move through connected campaign stages, using weapons, healing supplies and coordinated movement to withstand infected hordes.

Four-player campaigns and other modes

The main campaign supports up to four human players; computer-controlled survivors can fill empty team slots. Survival and Realism provide other cooperative challenges. Versus and Scavenge also feature competition between teams and are not simply larger cooperative campaigns.

Current platforms and crossplay

The English Steam listing supports Windows and SteamOS/Linux. An older Xbox 360 edition existed, but a current PC-to-Xbox crossplay arrangement is not confirmed.
