Welp, i think i'll try to add something very crazy to the RPM Map!
Riujin Mercinaries HeadquartersHome base of Magnus Riujin, it was originally the starcruiser Magnus used to come to RPM. Upon landing, he hit the button that turned it into a massive facility complete with MRN-8637 ARMAGEDDON Plasma Photon Cannon on the top and a MRN-422 Multi-Purpose Defence Turrent on the left side of the base. The Facility is very well equiped appart from the Auto-Turrent defences, boasting 6 Holographic Training Rooms, 30 individual rooms, a Cafeteria, and a Game Room that is larger then should be possible, but Magnus claims the base is bigger on the inside then on the outside to accomidate all the stuff(It's really just underground). Magnus obviously has his own room in the base, but nobody has ever managed to follow Magnus to it.
It should also be noted there's a large Hangar bay on the top floor with room for around 20 fighters/mecha. There's also a room in the basement that looks suspiciously like the inside of the Apature Science Research Facility and has a radio that constantly plays "Still Alive" in it.
