Pieces strewn throughout the game. The more of them you collect, the more cheats
you can access. On the left are the number of Intel Pieces collected, and on the
right are the cheats that are unlocked, with an explanation of what each does.

* 20 "Slow Mo Ability" Game plays at 40% normal speed.
* 30 "Infinite Ammo" Just what it says.
