Hey,
since I'm a huge fan of "tower defense" I wonder if it is possible to modify the level Beta 11, in which you are under permanent attack by the Collective and have to evacuate your troops and hold your base.
The idea is simply that you have an hour or so to prepare yourself and then be constantly attacked by more and more forces until you finally collapse at one point.
I consider the map already quite suitable, so all there is to be done is to change the counter, raise the number of the opposing forces and maybe make some more techs available.
Can somebody do that?
