I just don't get left 4 dead ,,,,Honestly from the graphics point of view it looks like a PS2/Xbox game.the gameplay is also what we have seen millions of times,,,,,well co-op zombie shooting is fun but the setting and the environment and graphics are not on par with Gears of war at alllll.
I honestly think if it has to compete with gears 2 it will get crushed.(both are co-op shooters ,,,one with excellent production value and one with last gen graphics/gameplay)
