Global Warfare (GW) is a multiplayer modification for Half-Life. The project was the brain child of Aggro_Boy, Sasquatch and alX, who formed the original GW team.It uses the GoldSrc engine, but has some unique gimmicks added to it that cannot (or rarely) be found in other modifications. Such additions include: Lens flare effect, weather effects (rain and snow), its own particle engine for debris, and 3D muzzle flashes. Beta 1.0 of Global Warfare was released on June 8, 2001. Global Warfare was presented at the 2002 Half-Life Mod Expo in Dallas.
