Hints

Rocket Stage Hint:
When you're in the Rocket Stage, you need TNT to blow open the doors to the rocket launch pads. You should have just enough TNT, but if you run out, don't worry! You can use your bazooka to blow open the doors to the rockets and destroy the rockets themselves. This comes in real handy if you use a lot of ammo like me!

Tin-Foil Uniform:
Enter tnmn as a code to get the tin-foil uniform but its not armor.

Pissed Off Vikki:
When you go to boot camp kill every green guy you see and then when you get to the end of boot camp where you have to jump onto the 7 platforms when your done and you go to the door where vikki is standing she will have grey clothes on and she will be shooting at you with a bazooka.
