Crime City is an Operation Flashpoint / Arma private game-mode with too much to do.
I'm porting this to Arma 3 once the Java API is released, and for now I'm re-coding it from the ground up for Garry's Mod.
Features included ( And I hope to bring most, if not all of these to Garry's Mod from OFP/Arma and then to Arma 3 )
