Named Game of the Year by over 50 publications, Valve's début title blends action and adventure with award-winning technology to create a frighteningly realistic world where players must think to survive. Also includes an exciting multiplayer mode that allows you to play against friends and enemies around the world.
This is a different SinglePlayer level. This level is made to be a replayable(by me too) singleplayer deathmatch/botmatch against those cool Human_grunts. Just try it......many times.
