About this game
Upgrade the CARS is a 3D driving runner where every gate you pass changes your ride for better or worse. Steer through green plus gates to boost your engine, body and top speed, and swerve around the red minus gates that strip your hard-earned upgrades. Each finished run pays cash based on how far you pushed your build, and that money goes straight back into your garage: new parking spots, fresh cars to unlock, and a texture shop to restyle your collection. Push deep enough into the track and giant kaiju start blocking the road — you'll need to mount weapons to blast through them.

Green plus gates apply a random upgrade to your car's engine, body or speed. Red minus gates remove upgrades, so steer around them whenever you can.
You need weapon upgrades from the shop. Once your car is armed, your firepower automatically clears kaiju as you approach them.
