We still deciding what engine we will use, but it looks like we will take unreal engine 3.
Forgive my rudeness, but does this mean you're still on the stage of planning, and already have little/some/all assets?
It's a long journey you know. I didn't quite expect unvanquished to make it this far, but if they did i'll assume you'll as well and hopefully not make a blunder like what volt did to his project.
Rotacak is quite different then volt.
Check his 3rd team mod, where he made a new team (robots) with aliens+humans battling together.
I'm quite sure this game will be released, but ofcourse, not over a span of 1,5 years.
