I accidentally broke out of the Ishtar Sink this evening whilst I was exploring. It's the spot across from the room that the fallen vandals, dregs and shanks come out of when you are coming from the patrol spawn point (right fork). It's not a huge area, but it was a bit problematic because every time I killed myself, I spawned back outside the map and couldn't get back without going into orbit. Don't know if it's something you care about, but thought I should let you know regardless. Thanks for an awesome game! I'm loving it =]
