gm_holdout

Map based in a zombie apocalypse or combine assimilated city. There are working turret, npc spawners and a 3d skybox. Next version will be bigger, have an extensive underground complex and more.

Edit: I always wanted to make a second version back when I made the first, but I kind of stopped making source maps after Experior and moved onto game projects and other game modding. Maybe one day I'll come back to a v2 holdout, perhaps with the next source engine version that comes to Garry's Mod (if it ever happens).
