The spiritual successor (& heavily influenced) to the original Half-Life 1 mod, Brainbread.
Right now this is still in it's early stages but more maps & features are soon to come, including implenting army ai. There is also a small but growing mapping community on their offical forums.

The original Brainbread, like a lot of other great HL1 mods, never quite made it to the source engine.
