BeefjackThe huge singleplayer mod – around eight hours long in this incarnation – takes everything before Xen in the original Half-Life and entirely recrafts it in the Source Engine. It’s a mod, rather than a standalone game, but it’s soon to be available via Steam if you require that for your PC gaming, and it only requires that you have the Source SDK installed. Half-Life 2 is not required. Plus it’s absolutely free!
