[NOT MINE] Left 4 Dead by Crimsonfang9

Description

(CONTAINS: Blood)(2+ PLAYERS) Pennsylvania suffers an outbreak of a highly contagious virus causing extreme aggression, mutation to the body cells, and loss of higher brain functions. Two weeks after the first infection we've took refuge at an apartment rooftop. We've prepared ourselves to head out to the streets in search of rescue. OBJECTIVE: Work together to blast your way through hordes of infected to reach the Safe Rooms. WARNING: Level will glitch if you rush through the whole level without killing.
