Unlimited Energy Sword


 * Note: this glitch only works on single player

Summary
Go onto a two part level. Then on the first part, grab a sword and use it until it is empty. Instead of switching it out, keep it and use another weapon. Then, after the second part of the level starts, you will still have the handle. Even though you get the message saying "out of ammo", the game will mistake it for a sword and this glitched sword will have unlimited ammo.

Levels it works on

 * Outskirts/Metropolis
 * Arbiter/Oracle
 * Delta Halo/Regret
 * Sacred Icon/Quarantine Zone

This glitch can also work on the last 4 levels.

NO other weapons are able to use this glitch.
