why is it that the player has 6 inventory slots but even if you only get one gun and one rocket launcher, you can't get the other rocket launcher?
how about flamethrowers? like the WWII kind?
Say, I had an idea, how about turrets! they would be the same as the gun turret on the top of tanks except they would be stand alone vehicles that could not move on there own so they would have to be picked up.
