Fake Pause / Invincibility
At any point in the game, press the Guide button and immediately press Back. You must press guide a fraction of a second BEFORE you press back. The guide will come up like normal so leave the guide and go back to the game. You'll notice that the game is paused yet everything is still moving! Enemies will still fire at you and everything will move except you. You can't move of course but an interesting property is that you cannot take damage or be affected by ANYTHING. That's right! You are invincible while it's paused! Use this trick on the Fabricator for an easy win! You can also start a swing and do the glitch to fly through electrical gates or other obstacles without taking damage!
