Spring RTS Engine

I hear CA/ZeroK has been wanting missions and I've been looking into it. There's one thing that would really help me though. There appears to be no "campaign only" units (like a galactic gate from TA or some random facility ala supcom). So far the only thing I can think of for campaign targets are commanders and those power cores. There's those chicken buildings but I don't want to implement chickens just yet.

You have 2 options:

you can add extra unit to your mission only.
Just go where its saved and add new unit directly there :)

Or we can add it to game itself.

zero k also needs more super units...
