Me and my brother discovered a 2man glitch that can completely skip entire levels.

To do it the host must hold a second player with both hands and the second player must then mash the reload button, this sends the host flying at great speed towards player 2 if performed more and more time before the host lets go, at which point the host will be shot flying with midair control.

We managed to complete Aztec in almost under a minute on Xbox 1.

We call it the "Giga Jump" for obvisous reasons.

Wow almost like team fling huh
