This game had some major potential and I was really enjoying it....until I made it to level 8 of 10 and a glitch occurred and I could no longer fire a weapon. I tried everything....turned on and off several times...reloaded the mission. Nothing worked. Looked it up online and apparently several others had the same problem and the only thing to do is start all over....yeah right so that can happen again. I think I will try a different game. What a shame cause this could have been a good one.
