Half-Life Decay is an updated version of the mod that ports the cooperative expansion Half-Life: Decay, originally released only on PlayStation 2, to PC. It fixes bugs and improves visual and sound effects. The mod allows you to play through the entire campaign in its original form, solo or in co-op.
