A love letter to the Marathon series, MINERVA: Metastasis was an aborted attempt at a singleplayer Half-Life 2 mod by Adam Foster. Because of this mod, Foster was hired by Valve, and the planned follow-up was cancelled. Still, if you like Half-Life 2, snarky AI companions, and impressive level design, this is short and sweet mod that will at least temporarily scratch your itch for any new canon Half-Life content.
