Might be good to have a place to hang out, like a big post-apocalypse town. The actual battles should take place in the battle zones, in the town you cannot use weapons or you would need to pay for the ammunition. In the town center you would have a parking place for space ships or a big teleporter which puts you on the dropships. Beside that you can also find shops for special items and persons which give you jobs/missions.
I don't like the idea of street gangs though, since this should not be an era clone and it's not realistic for a futuristic scenario.
