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.
Freeman is going through some terrible places, he's teleported to another dimension of merciless monsters, a dark dank place where you kill monsters to get through (some are ghostlike). You won't get much ammo and there's lots of monsters. So just enjoy it as best you can.
Well this is good mod actually
Well where is the sequel 3?
