ALmost every game I am in someone has an opinion about glitches. I mainly play on town in survival mode so I will use that for examples
Throw your grenades into the pack-a-punch lave pit. Throw the monkeys in the lighted room. Lay down by the Double tap machine.
I have been keeping a rough track of how many Max Ammos I get by throwing my grenades into the pit and when I do not. It is roughly the same results whether I do or not.
It would seem keeping your monkeys rather than waste them in a lighted room would be far better for surviving.
So any truth in this or just plain theory?
