Tried the Left 4 Dead Demo out last night, found it to be some good fun. The graphics are not bad, the animations are perfect and the gameplay suits the name (and game) very well.
Left 4 Dead is a FPS (first person shooter) where one chooses from four different characters in a squad with a mission – to survive a brutal infection that has plagued a city. At your disposal are several different kinds of weapons suited for different environments.
It exceeded my expectations, although as a demo it was too short =) . I am longing for the real game, I must say!
