They better get somebody to develop the drive for them first.

Well, one of the characters, the R&D boss, is an old Russian space
engineer. And their motto is "faster, better and now with even more
cut corners!" :-) So I would not be surprised about them using a
lox-kerosene engine.
Apropos drives, could a Nerva nuclear engine be converted into a
stationary reactor for power production?

I have definite plans for introducing the wonders of accidental space
ecology in the game. One of the things they will need to get working
is a small ecosystem to supplement their food and recycle waste. Space
molds might be more dangerous than meteors to the mission.

However, I have not heard anything about any colonies on Mir's
*exterior*. That sounds rather unlikely, especially if they were
eating low-energy stuff like quartz.
