My brother just got the game and I hyped it up cause I've been playing for two weeks now and I have never heard of this glitch. He got the game and we jumped on as a team the first day he got it. He was screaming that when he used the SCAR that the gun only shot 3 rounds and stopped?????? I didnt understand what he was saying, the SCAR is automatic?? Does anyone else have this same issue? He is ready to get rid of the game, but I'm telling him that the game is great. What to Do?
