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.
Ultra Definition model pack by R1chard for Point of View is awesome, but its crosshairs are not very convenient. They're very large, thick and bright (with the mod consisting mainly of darkish locations), and are likely to pop out of the scene when playing in stereoscopic 3D. For the good old one-pixel-thick circle for Xen hands and cross for (dual) hornet gun, extract this in the mod folder AFTER UD pack! Enjoy!
