Weapon Swap Glitch

Weapon Swap Glitch...

It's possible after u shoot all your weapons (example lazers) to then shoot the same weapon again (lazer) even though u take another weapon (missiles).
Example I'm in the game I take 2 lazers in Mayan and shoot both lazers, I now have no lazers left, I then take missiles and the first shot I shoot is a lazer (meaning the former weapon I had).
This weapon swap glitch works in all maps and works with all weapons.

We won't spoil this glitch yet...
