Level Secrets:
Construction Yard:
Destroy door on the crane in the middle of the map. You can control the crane by getting inside and then pressing the X button when a car moves inside the target area. Make sure to drop them in the fire area. When you come to the area where there are 3 rooftop ramps, choose the very left one and it will take you to a conveyor belt with full health on it. After going to the other side of the belt, there is an object on the ground that can be blown up, revealing a secret basement.

Neon City:
Follow the train tracks up to the 2nd level. On the side that the teleport is on there is a little ramp you take to break the glass for some health and a couple of weapon pickups. In that little room shoot the wall pannel that is cracked. Once it blows up there will be a green "Train Icon" Sit on the icon until you get picked up by the hoovering train. It will take you to the secret balcony which has a full health and some good weapon pickups.

Road Rage:
Look for signs that say East Erie. Follow their pathways until you come to an area where you see a blue glass building that is behind the concrete road side. You can blast through this to find a full health, and good weapon pickups.

Bedroom:
Break the lamp to get lightning, and then make sure that everyone is in middle before you use it. There are several gasoline bottles that can be destroyed, revealing secret passageways to full health and good weapon pickups.

Amazonia B.C.:
Basically try to go from ramp to ramp until you reach a portal that will take you to the top of the ring area. At the top there is full health, lightning, and other stuff.

Oil Rig:
You can destroy the helicopter with an auto lob, or other elevated missle, but I wouldn't suggest doing that. The helicopter drops off a half-health every couple minutes on the pad, but if you destroy it, you only get power missles and a couple other weaker pickups.

Minions Maze:
Everything in this level is at the very top, and the underground basement. Both are in the middle.

Carnival:
To get inside the ghost house, use something to blast the floor in front of the door with. There is also an initialed stone at the bottom near the roller coaster with a breakaway floor that takes you through a narrow passageway filled with gravestones. The full health is on the roller coaster, and to get the lightning, turbo off the coaster onto the big top tent. The best way to kill Sweet Tooth on this level, is to get the proximity mine pickups, and force him to follow you through the ghost house and onto the roller coaster. Don't try to face him close up, because his special will tear you up.

Hints:
Defeating Sweet Tooth:
Collect as many Freeze Bombs and Remote Bombs as possible, then get on the tent. Set a Remote Bomb and a Freeze Bomb down and wait until Sweet Tooth gets on the tent. Freeze him, blow him up with remote bomb, then hit him with your special. If you get caught in his special in the process, just press Up, Up, Down, Down and you will usually break out of it.

Press Up, Up, Right to use the shield when the special attack hits you, then quickly run and attack Sweettooth with your best special. It is easier if you use Minion and Sweet Tooth to defeat him.

Try using remote weapons by Freeze first, then Bomb. When caught in his special, put on your Shield or Hyperspace. His special will not find you if you are invisible.

Defeating Minion:
Use the hit and run tactic to defeat Minion without using the "God mode" or "Sweet Tooth" codes.

Drive up walls:
The Microblast car (and possibly others) can drive up walls. Aim your car at a wall, stand back a short distance, then turn on your turbo and jump at the wall. You should be able to drive up the wall. If not, try hitting the wall at an angle. You can reach a lot of secret areas in the game by doing this.

Secret Area in Amazonia:
Go to the magnetic jump closest to the semi-pyramid with the partial health. Try shooting Power Missiles at the walls to the left of the jump. This secret area consists of a full health pickup and a huge acid pile.

Riding the bus in Neon City:
Jump into the glass by using the ramp. Then, shoot the wall on the left with missiles or your machine gun. You will find a small "bus stop". Stand there and wait until the bus drives by. The bus will hover you into the air. The bus will "drop you off" automatically. This area consists of a full health pickup and a lightning pickup.

Neon City subway and roller coaster:
Use Power Missiles to destroy the train that rides through the tunnels. When destroyed, you can get some more weapons. In the carnival, destroy the roller coaster to ride freely through. Failure to destroy these will cost you half or more of your energy
