Left 4 Dead 2 is a co-op first-person shooter where four players fight through zombie-infested campaigns to reach extraction points. You and three teammates face waves of infected humans driven mad by a pandemic, using guns, melee weapons, and throwables to survive. Each of the five campaigns breaks into chapters separated by safe rooms where you restock and catch your breath before the next stretch. Special infected—like the tongue-lashing Smoker or tank-sized brutes—force coordination beyond just shooting straight. Campaigns end with finale events: hold a position while waiting for rescue, then make a desperate sprint to the vehicle. It's designed for four human players, though AI fills empty slots. Runs demand communication and cover fire, not lone-wolf play.
