Stay with the incompetent AI or die!
User Rating: 9 | Left 4 Dead X360
Left 4 Dead is yet another awesome game from Valve, the creators of the Orange Box. Left 4 Dead is meant to be multiplayer, like Team Fortress, but Left 4 Dead can also be played single-player. Unfortunately, it's a bad idea because the allies you are stuck with, like most team AI in video games, are incompetent. Bill will shoot at a Witch you try to avoid, Zoey will walk up to the Witch, Louis will steal the final health pack or pain pills from you and still take the most damage, where as Francis will run in front of you when you fire at infected or special infected. There are quite a few choices you can make in Left 4 Dead, i.e: avoid or shoot the Witch, or which weapon you'll pick. There is an AI Director that will change what happens in one of the four campaigns, the AI Director will change what enemies you'll face, how many infected are there, when an attack from a horde will come in, when a tank will come in and from what direction, where weapons spawn, where pipe bombs and molotavs spawn, etc. There's survival and versus modes too. Overall: a great game.
