Megabuilding H10 as close as I could get to the bottom of the atrium without dying (floor is lava programming, any area you could fall into is autodeath, but floor covered by a ceiling was fine)
The unit above V’s penthouse from The Sun. Same layout but no furniture, no doors, no fixtures. There’s also some rock texture randomly thrown in. I hadn’t noticed during The Sun that there was an elevator and here there is a shaft with an elevator car at the bottom.
Through another series of well timed jumps from inside Megabuilding H10’s architecture (and a lot of trial and error) I was able to make it back to V’s penthouse from The Sun. although the penthouse itself was locked.
