Zombie Master on the Source 2013 engine. Reviving your favorite Source FPS/RTS!
Game files for Zombie Master: Reborn Beta 6 (Linux). Source SDK Base 2013 Multiplayer is required, which you can download in the Steam library Tools-section. See changelog in the Steam group.
Had to add "-steam -steam" to the launch options to be able to join VAC servers, else I would get an error message about being in insecure mode.
