Multi-player: Invincibility:
In any multi-player level, press Start. You can be shot at, but receive no damage. You cannot move, but it is better than dying.

Upgrade Prices:
The prices for upgrades will drop (sometimes drastically) as you progress through the game. When an upgrade is offered by the Barter Droids it will be continued to be offered until you purchase the upgrade. Items such as the Scatter Blaster, Rocket Launcher, etc can be found later in the game (dropped by enemies) for free.

Multi-player levels:
Collect the corresponding number of secret chips during campaign mode to unlock the corresponding multi-player level.

Corrosive City: 110 secret chips
DMA Death Sphere: 40 secret chips
Mac mines: 138 secret chips
Matt's Big Gun Fun: 8 secret chips
Morbot Land: 15 secret chips
Ruins: 60 secret chips
The Coliseum: 85 secret chips
The Reactor Factor: 25 secret chips
The Trenches: 4 secret chips

How to beat Scouts:
To deactivate a Scout quickly and easily, run up to it, preferably from behind. Get as close as you can before it notices you. Use the Scatter Blaster on it. Do not use coring charges or rockets on it; they take far to much time to re-fire/reload. The Rivet Gun is too accurate, and there are only five rivets to a clip. The Mining Laser should not be used, for obvious reasons. If it gets too far away to use the Scatter Blaster, get the SPEW out and use that.

How to beat Sentry turrets:
When dealing with a Sentry turret, get around the back of it and jump onto the platform on its back. You can shoot at it, but it will not be able to shoot back. When it turns around to fire at you, you will still be behind it. It will just end up turning around and around.

How to beat Mils:
Mils are a lot less likely to "know" what is shooting at them if you are in a vehicle.

Secret chips:
There are a total of 143 secret chips in the game. There are 104 hidden chips to find, and 39 speed chips. REMEMBER: There are no speed chips for levels 1, 18, and 37.

Additional barter droid dialogue:
If you visit Shady and Mr. Pockets (the barter droids), then leave without buying anything, they will say something other than their usual set of parting phrases.

Grenade warning:
Every grenade you launch can hurt you if you are close to it.

Drive on the wall:
On any level that has the car with the claw, have the wall on your left or right. Then, strafe left or right and you will begin to drive on the wall.
