Unlimited Sword Ammo

[SmokiestGrunl]

You can do this in any two-part Campaign missions (i.e. Outskirts and Metropolis). If you finish the first level of the two-part mission with a sword with no ammo, you'll start the next level with a sword that has unlimited ammo. Though the sword doesn't show up when you arm it, it still makes all of the sound effects and acts exactly like a normal sword.
