Basically the first 6 levels fused together as 1 level.
Currently this build is an attempt at getting all the Doom 2 levels in one level. When I have fused all the Doom 2 levels then I will consider combining the entire Doom 1 fusion project with the Doom 2 fusion project. This would mean Doom 1/2 would eventually become one game, be a sort of open world style Doom that would allow players to fight demons anywhere in the classic Doom.
The Doom has an episode?
This is the first episode for Doom as one level with all the maps on the same level, I'm currently working on adding episode 2,3 into the same map and this will eventually lead to all the episodes being on the same level. ;)
