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 very short puzzle-map for Half-Life.
To play: put the file in your half-life/valve/maps folder. Start Half-Life. Got to console and type map sk1.
Plz give comments and critics. If you like it I will maybe extend it and make more maps of this kind.
