In the beginning, there was Half-Life, Valve software’s blockbuster debut. With its engrossing story line, skeletal animation system, and so-good-it’s-scary AI, Half-Life blew away the gaming world, earning “Game of the Year” honors from over 50 publications, and winning legions of rabid fans. The Half-Life universe grew with the release of Team Fortress, Opposing Force and, most recently, Counter-Strike. These games pushed the Half-Life engine to its limits and beyond, adding exciting new story lines, weapons, enemies, and multiplayer challenges. This indispensable collection includes four finger-numbing, up-all-night, frag-yourself-senseless 3D action games. Play them all. See for yourself why PC Gamer declared Half-Life “The Best PC Game Ever”.
