maybe retexture a couple maps, like training maze and csl. im not sure theres a point to it, but maybe you could make a sort of training theme out of it. also for the unis, make a black full body suit with little hot spots marked out in red on them. have a training scenario for each method of combat (sniping, cqb, camping

). thats all i can think of right now, im pulling things out of my rectum.
