I do see the humour in a mod sneakily changing my title
Update: Megamur and I have been discussing episode themes and transitions for a while now, as a few have asked for.
Heres a general very rough plotline from bits and pieces of our ideas:
TNTR Episode 1: Seperate complex to the one from Evilution E1, Standard TNT techbases, usual fun stuff. The basic idea is that returning from Last Call, Doomguy traverses a different base, likely to get offworld to Earth. The moon still has dead remnants of the hell that faded away upon the IoS's death, which is why Sky 1's prototype is the way it is (feel free to make use of a few hellish defunct artifacts in places, likely outdoors)
TNTR Episode 2: Creepy, unsettling defunct base under a dark space sky. Escape transport ignores coordinates, takes Doomguy to the original gate facility (The one that was in Evilution's story) The villain of TNTR will make itself known over time, and interfere directly with the levels themselves; presence should be absent for first two or three levels, very low after first encounter, then gradually increase until its actively using the level itself to stop you; make the levels themselves feel hostile. End goal should be the original hellgate from Evilution that the marines locked down and experimented on.
TNTR Episode 3: Industrial tech-hell. Biomechanical computers, blood circuitry, bloody pipes and rust, a hell where human tech has been fully integrated with the demons, following on from Doom and Doom 2's increased usage of our tech over time. Megamur suggested that the entity behind this is the hellship itself, that has fused with the landscape itself and must be destroyed from within. As an alternate reality that diverges from Devilution, this is feasible, but I feel it steps on toes a little. Thoughts? My version is similar, but is definitely not the hellship.
