Left 4 Dead 2 (abbreviated as L4D2) is a cooperative first-person shooter video game. 
Left 4 Dead 2 is set during the aftermath of an apocalyptic pandemic, and focuses on four survivors fighting against hordes of the infected, who develop severe psychosis and exhibit zombie-like tendencies. 
The survivors must fight their way through levels, interspersed with safe houses that act as checkpoints, with the goal of reaching a rescue vehicle at the campaign's finale.
