Half-Life made its debut in 1998 with an engrossing storyline, a skeletal animation system, and enhanced AI. 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. Now, you can experience all these games with Half-Life Platinum, a collection of Half-Life games, including Game of the Year Edition, Opposing Force, Team Fortress Classic, Blue Shift, and Counter-Strike.
