Guns don't work. The m4, AK,USG all have a habit of just deciding not to except a magazine after reloading a few times (unacceptable) and also after shooting about 1 or 2 magazine its like your shooting bullets made of air also UNACCEPTABLE!!! Nothing like scavenging for 5 hours and then facing an enemy and unloading a full clip at point blank range and NOTHING happeneds, then they pull out their pistol and their bullets work. Youd think that when you release a game even in game preview the guns would at least work, after all it is a primary thing in this game....FIX IT!!!!
