Runes hiding places
Go to the corner of the second highest level of the gray tower. There is a hole on the side near the Hover that can be used to hide in. If two monster trucks are placed in the hole, one will go flying out. Drive on the road where Nitro and Hover are located. A small building will come into view after the jump. Use Hover or Diamond Invisibility to enter the building.

No shocks
Enable the "Low rider trucks" code and begin game play in two player mode. Collect a shrinker missile, then shoot it at the other player's truck. That truck will appear to be only body and wheels.

Wheelie on back wheels
Select the Scrap Yard race. Go to checkpoint 4 and plow through the breakable part of the fence. Then, backup to the unbreakable part of the fence. Keep holding the "Analog-stick Back" and when you get "Hang on" message, you will launch. When you fall from the air (keep "Analog-stick Back" the entire time), hold [B] two seconds before you land. Hold "Analog-stick back" + [B] and you should do a wheelie.

Glitch: Get stuck in last place
Select any truck and start the Voodoo Island track with more than one player. Between the start/finish line and the last checkpoint is a large jump. Skip the jump and go around on the track already you went on. The game will state that you are in last place for the rest of the race.
