Game Secrets, Unlocks

Glitch: This is a step by step guide to getting this glitch to work. Follow these instructions or it will fail.
Requirements: You must have the grenade launcher and two types of ammo (e.g., Grenade Rounds, Incendiary Rounds)

1. Put all items in item box
2. Put Grenade Launcher in upper-left item slot
3. Put Incendiary Rounds in upper-right item slot
4. Close box
5. Open inventory
6. Equip Grenade Launcher
7. Open box
8. Select Incendiary Rounds from inventory
9. Press ''A'' twice
10. Move cursor to Incendiary Rounds inside box
11. Press ''A'' twice

The amount of Incendiary Rounds in the Grenade Launcher will now increase. The number value will be graphically glitched. Close the box and open inventory to fix that. This also works for other types of grenade ammo.

This glitch will NOT work in the PAL ports of the game.
