Right it appears that each dome has 2 teleporters, each biodome is on its own map so when you hit M that is one biodome,
The apartments and docks, control room etc then appear on a separate map, which as yet doesnt have any walkways shown?
Im not sure of this but you cant scroll to any dio domes from the control room map, I hope this makes some sense
Ill go and time a run from one end to the other now .....
5 min continous run, and the mobs seem to differ all over
