Underground Base in Doom

IcyFresh's Underground Base is a Roblox map I always thought would work in Doom, so I tried it. The rooms are the same, the layout is the same, the flow between areas is the same. The goal was to make it feel like the same place on a different engine.
There's no exit switch. The point is figuring out the base: getting computers online, hitting switches, watching other parts of the map respond. It plays more like poking around a facility than running a level. There's stuff to shoot if you want it, but that's not what the map is about.
The sector engine can't do a lot of what Roblox can, so some geometry had to change. Some rooms, multi-floor rooms, overlapping space all got reworked. The key landmarks made it in. If you've spent time in the original, you'll know where you are within a few seconds.
