I just played patrol on earth with a friend and had pocket infinitie equiped and I was able to go in rasputins Bunker. I've just been able to go in the first Room, where you have to throw a grenade i this small Tunnel. But i couldn't do anything in this Room, just walk around. So i belive it's a glitch, but my friend and me were very excited. Later, i went back to Orbit and then to earth again, but the Bunker was closed
