Episode one of the Base Ganymede series for Doom 1. Sticks to vanilla limits, so all ports are supported.
Base Ganymede is an episodic doom 1 project set on one of Jupiter's moons named Ganymede which is sticking to vanilla DooM map limits. Planning on 3 episodes, the first was completed late 2009 and can be found in the downloads section. I'm aiming at another 8 maps. So far, M1 and M2 are completed with M3 well on the way.
