Hot Wheels: Extreme Racing is a licensed racing game that's based on the Hot Wheels brand of toy cars. It features a unique gameplay element where the vehicle you choose can transform based on the terrain you're racing on, with body shapes optimized for land, air, water, or all-terrain. It also allows for customizing the vehicle and all of the body shapes it can transform into, with the engine, wheels, wings, and other parts able to swapped to fit to your liking. Similar to other racing games such as Wipeout and Mario Kart, it has collectable powerups that can either be weapons or speed boosts.
somyeol for this run chooses to use an in-game code to give them the best vehicle in the game and unlimited gear changes and races on all the tracks in reverse in record time with copious amounts of glitchy zipping and RNG manipulation.
