Tips:

Rapid Fire
You ever wonder why there's such a long delay between weapon firing?
There is an easy way to fix this problem without going into the password menu and typing in the cheat code for faster weapon fire. First, make sure the weapons you wish to fire are as close to each other in your weapon inventory as possible, then fire off your first weapon, then quickly switch to the next and fire it, etc, etc. This MAY seem like a stupid tip, but it's actually very useful. (For example, let's say that the fire missles, homing missles, and power missles are all lined up next to each other in the weapon inventory-which they usually are if you have them-o.k., now fire your fire missle switch to your homing and fire, then to your power missle and fire--this must be done very fast to ensure
rapid fire)

SUPER EASY WAY TO KILL SWEET TOOTH--NO STRINGS ATTACHED
O.K. I know a lot of gamers and "tip givers" post ways on how to kill Sweet Tooth in an easy way, but this one is so easy, it's not even funny. When you've killed everyone that needs to be killed in The Carnival, make sure you have three proximity mines. Next, go into the portal that leads to the top of the building directly next to the tent. Make sure you have not moved AT ALL when teleported, lay all three of your proximity mines, and get within safe distance, but stay on top of the building. Sweet Tooth, being the idiot that he is, will sooner or later go onto the building with you, but when he does, the proximities will blow him off the screen, leaving you the victor. Sound Easy? It is. Just make sure he is not right behind you when you go into the portal and lay these babies--it will take some time to lay them. Also, make sure you had not had any confrontation with him when doing this to ensure you the most safety-AT LEAST make sure you are not in his special when laying the mines.

Turboing in Mid-Air
These is probably the least important trick in the book, but is still useful. Let's say you have a guy(or girl) on your tail, and you want to juke him out, speed off of the edge of a ramp and turbo backwards immediately to get back on. I certainly do not find this trick THAT useful, but maybe you will.

FOUR PROXIMITIES AT ONCE?!?!
This is VERY difficult to do, but it is possible with a VERY fast vehicle. Obviously, the trick is to lay four proximities in one area and to speed quickly away. Also, and this is with any amount of proximity mines, do not just keep pressing the fire button to lay mines--when you lay your
last one, it will automatically switch to the next weapon in your inventory, and if your still firing--KABOOM!! The coolest thing about Twisted Metal 4 is the fact that even though there is a firing delay, it only pertains to the weapon your firing. Therefore, you can have one projectile/mine left for weapon, and if you press the fire button continuously, it will fire them all pretty much at once.

The Rear-Attack Trick
The biggest gliche in the game is the rear-attack trick. Although they tookaway the regular rear-attack from Twisted Metal 3(left, right, down) that allowed me to fire rear-attack so fast, they conveniantly left the rear-attack trick. What is the rear-attack trick?, you ask. Well I'll tell you. When your completely out of weapons, and you do a rear-attack, it will fire the weapon you had last, even though it is not there!! This is especially useful for The Maze with the lightning! Just make sure you have nothing in your inventory when you finish off your last lightning and you will be able to do unlimited lightning until your next special pops up.
