[PC, Steam] Fumes $17.56 (20% off) @ Steam

From the steam page: "Arm your vehicle with deadly weapons and roam endless wastelands in this fast-paced single-player car combat game. Collect upgrades for your car to melt enemies and giant bosses in this bizarre world. Retro vibe. Retro cars. Retro gameplay!"

I highly recommend it. It just recieved a loot balance update. There is a demo that is a must try.
