Bad Biker
If you hit one of the Japenese riders or get a ticket from a cop, you will become part of the bad biker gang. You will be able to use the weapon that the gang favors the most.
Buy any weapon
When you are buying bikes press: Up, Down, Left, Right, L2, R2.
Easy "Blast 2X"
While racing, hit the ZOOM OUT button then hold the REARVIEW MIRROR button and release ZOOM OUT. You should now have Blast 2X without having to do the annoying "looking back" part.
More speed
Press Up, Down, Up, Circle, Triangle for more speed.
Shortcut for Level 2
When you are going from Kaffe Koma to the Der Panzer Club there is a shortcut that will shave about 2 1/2 miles off the race. It is a challege to do but worth it. Go straight for 3 miles then hang a left. It will tell you to go straight. Ignore the wrong way sign and just follow the road to the Der Panzer Club. This is very helpful. I would only suggest this shortcut for experienced rashers.
Steal Weapons
If you punch another rider with your bare hand while his weapon is drawn, you will be able to steal his weapon.
Super Punch
Press Up + Circle and hold. When you are ready to punch, release.
Ticket Prevention
When getting busted, pause and restart the race. This will get you out of a ticket and save you money.
