Super Gun
Do challenge 18. If you don't get this cheat, try it again with difficulty set on very hard. The easiest way to do this is to get a car with pretty good speed (around 75 to 85 in stats) and with close to or maximum turning. Once you do it, you will get a secret gun that can take out any car ( except Otto's) with one shot, even a surfing' school bus.

Easiest way to beat the last mission
If you have unlocked it, use the Surfin' School Bus with the Energy Shield gadget. When you start, you have to go through a mine field. Keep using your energy shield. When you meet Rupert, you must disable him. Use your Energy Shield until you get a gadget that you can attack with. Disable Rupert and his henchmen if they get in your way. Then, you have to go destroy the computer with the special gun. Find the special gun and destroy the computer. Otto will appear and drive off. You must chase him. There will be more mines, so use your energy shield again. When you catch him, disable him with your special gun because it will take him out with two or three hits.

Strategy Guide and Level Passwords
Here are some tips on racing Hotwheels Velocity X.
To win races, no matter what car, you must constantly tap the A Button to put on sped bursts. To do this, keep doing high point stunts on jumps to make up the Stunt Points needed to perform the speed boost.
Until you get the car Screamin' Hauler (driven by Slick), always use Purple Passion, as it is the fastest and strongest. To beat Slick, keep using the speed boost and fight him with gadgets, such as the Zapper.
To beat Nitro, you have to perform advanced stunts while using speed boosts to get ahead. If you beat him in a race, but don't get the required amount of points, you will lose. (Oh, yeah. When you beat him, use his Arachnarod car until you get a better one.)
Fastlane is really fast. But she and her cronies are very weak. Your best bet would be to alternate speed boosts and weapons to destroy them and get past them. Oh yes, watch out for their bear traps. When you win, Fastlane's Surf Crate car is fast, but the Arachnarod is still better.
Now for Rupert. Racing him is tough, as he is very smart. Keep using speed boosts with a car with good speed, acceleration, traction, and armor. When you beat him, use his car, Maelstrom, to beat the next boss.
Belcher is a dirty racer. When racing him, blast away at him and his cronies while using speed boosts to get him. Watch out for his shortcut move!
To beat Otto and MetaCog is fun. Use Maelstrom to beat all the fake MetaCogs, then go after MetaCog. Otto and MetaCog will use their prototype energy shield to shield themselves against all of your attacks. To hurt Otto, stick by him so that MetaCog will bump him, damaging Otto. Then Otto will use his Otto-sizer. This shrinks you every few seconds and makes him bigger. Keep making MetaCog bump him until you win. Then you will get the ultimate Hotwheels car, Shadow Jet.
