Half-Life: Decay vs Half-Life: Source
Side-by-side comparison of features, pricing, ratings, and alternatives.
Half-Life: Decay is the third expansion to Valve's iconic first‑person shooter, released exclusively for the PlayStation 2 in November 2001. Developed by Gearbox Software and published by Sierra Entertainment, the game retells the Black Mesa incident from the perspective of two research scientists, Gina Cross and Colette Green, and is designed for split‑screen cooperative play. The experience blends classic shooter action with platforming and puzzle elements, requiring both players to coordinate their actions to progress through the facility, repair equipment, and survive the resonance cascade aftermath. Its unique co‑op focus makes it a distinct chapter in the Half‑Life universe, emphasizing teamwork over solo heroics.
Half-Life: Source brings Valve's iconic 1998 first‑person shooter to the modern Source engine, delivering enhanced lighting, realistic water, and ragdoll physics while preserving the original story. Play as Gordon Freeman, a Black Mesa scientist thrust into a chaotic alien outbreak and government cover‑up. The port adds vertex and pixel shaders, soft shadows, a 3D skybox, and improved physics interactions, giving fans a fresh yet familiar experience on Linux, PC, and Mac platforms.
