This seems really stupid but it is annoying the hell out of me! Is there anyway I can change the ammo type in my rocket launcher without having to fire off all my shells? I'm trying to fight the plant thing in the guards area but need to change my ammo type from acid from fighting the snake into fire. I have so far only been able to change my ammo type after firing all my shells off, but it was pretty annoying to waste a load of rocket rounds when fighting the snake! I don't want to waste acid rounds while fighting the plant. Thanks!
