Some of the relatively new maps are not included in the Open Space mode. I propose those get included so we can explore them.
These maps are:
I also propose their location.
Spoiler
Depot 15 would be great next to the main station, and since there is an unused “red gate” at guardian 17, I thought I would put it there.
Leviathan. Catacombs should obvioucely be at leviathan planetoid, so I put it there. Also, Numerous quests could be oriented on that map from Theta station.
Proving ground Nova-31 has captured dreadnought-ish background, so I put it there. There are a few unused red gates at warden outpost ruins.
Omega station would be nice somewhere to use up the red gates. One is at New Eden, and the other at asteroid field next to the dreadnought at Ice belt.
