What you think about move to Spark Engine?
It's almost done game:
-most models of marine should suite Unvaquished/Tremulous design, weapons same.
-aliens should have new models but its still les job than developing Unvanquished from current level.
-so mainly job will be gameplay programing, in lua or source code.
The biggest problem can be optimalization, how Spark will handle with many buildings on map, propable engine net many optimalizations...
