STUNT TRACK CHALLENGE:

A side-scrolling stunt racer where the player is rewarded with speed bonuses for each stunt. Tracks are based on the toy tracks every child is familiar with. The game is somewhat similar to Excitebike in that the player must make jumps and land them correctly in order to complete each track. The player has the ability to roll and spin while in the air and is rewarded with a speed bonus for each successful stunt. The bigger the stunt, the faster you go. The game features 6 licensed Hot Wheels cars and 6 tracks. There is also a two player link mode.

WORLD RACE:

Compete to be the world's greatest driver in the most intense race ever created - The Highway 35 Circuit. Do You have what it takes to master treacherous jumps, death-defying loops, and win the Hot Wheels World Race event?

Hot Wheels Highway 35: World Race, celebrating the 35th Anniversary of the Hot Wheels range, features dozens of authentically modeled Mattel Hot Wheels cars.
