Half-Life is a science fiction first-person shooter video game developed by Valve Corporation and it’s the predecessor to the successful Half-Life 2. Published by Sierra Studios, the game was first released in November 1998 for PC and in November 2001 for the Playstation 2 ported by Gearbox Software. Half-Life uses a heavily modified Quake Engine version, which was named “GoldSrc” or “Goldsource”, and was able to render in two application programming interfaces, which are Direct3D and OpenGL. The successor of the GoldSrc engine is the Source engine ran by Half-Life 2. Half-Life won over fifty “Game of the Year” awards since its release, and sold over twenty million copies.
