Left 4 Dead

This game reminds me a lot of the "Dawn of the dead" 1978 version. A story evolves around four survivors immune to a virus infection that has spread around infecting and turning people into bloodthirsty zombies.
There are are 4 maps in total and not really linked. Each map is split in 5 chapters. You basically play as one of the survivors trying to get to safety. One of the strongest side of this game is AI. Zombies will spawn and behave unexpectedly so each map will always play different.
In terms of weapons you can use pistols (one or two), shotguns, riffle, semi and sniper. You will also find molotovs and pipe bombs.
The game is great on it's own but it really gets better when played with friends. Players can join and leave as they please without effecting the game. You feel like you need to go a get a drink of water so you can calm down your fear Very Happy, press start and choose take a break and bot will take your place.
Even better then co-op is the multiplayer versus. Mpas are the same as single player and co-op and you can have up to 8 players in the game. 4 will start as survivors and the other 4 as specially infected. Infected can respawn but survivors once dead they can't respawn for that segment. Each chapter players alternate from being survivors to being zombies and vice-versa. There is a lot of sneaking, tactics and strategy involved as zombies can choose where to spawn and they can see survivors all the time.
Hard to find any negative features but if one wants to be picky I could say that I wish there were more weapons and more maps available. Animations of zombies and other survivors is great but I don't like the character you play movement much as it feels to me like you're gliding rather then walking/moving (similar to Half Life 2).
All in all great game SP - 7/10; MP - 10/10
Final score 8.5/10
