[PS3][Unknowm] Class-based platformer zombie game.

I was just thinking about the good old days when me and my friends used to play coop games on my ps3. There hree particular games we always used to play and for the life of god, I cannot remember the name of the third one.

It is a 2d platformer, class-based story-driven zombie game. It was about four college students right after an outbreak escaping to the local metro. The four people were the four different "classes", I always played as the football player.

The first few levels included getting power supply for the metro and getting it running. There were also different guns hidden around the map. I also remember using them was a pain in the ass, as you had to aim with the right stick but it was too sensitive and the flashlight was attatched to the gun so without ammo you either saw where you were going or you were fighting with your melee

Anyone knows what I'm talking about?
