You should try antistasi plus by socrates or the reupload. I have been tested all the antistasi around (official/community/plus) and it is the best for me.

We are 3/4 people btw

Community version is really more up to date. If some bug appears, they will be probably much faster than me on fixing it. From time to time I update and I steal some code from them on things which worth it :)

This said: this version still has several AI improvements which the community version lacks and I dont know why they are not porting as they make the mission more interesting. Generally speaking, any improvement on antistasi should focus 90% on AI. Building bases is ok, but being ambushed by AI is much better :)
