A brilliant game. Valve has once again broken the ground like Tank and thrown it in your face. Arm yourself!
Once again, the legends at Valve have created something special for us. A game where you and your friends (or A.I if you choose) work together to battle an seemingly endless onslaught of zombies. We all love zombies as long as they aren't ripping our arms and legs off. The weapons and health are well placed (expert/normal modes) in that area where you would need them most.
Graphics and game play are superb. The sounds set the tone and mood of the game. Game play can get a little choppy in areas but nothing a patch or two can't fix. Subtle ambient details wallow around the scene as you as your team battle through the darkened hellhole of a city collapsed. Multi player is just as fun. Valve's Achievements system has been brought to this game and adds more replay value to an already addictive game.
Can't wait to see what new maps/expansions are in the works from Valve and the huge Steam Community. Good stuff here and a worthy candidate for PC Game Of The Year.
