Turn junk into valuable products. Build relic combos in an offline roguelite.
A broken phone. Three hungry machines. One more floor. SCRAP REACTOR is an offline engine-building roguelite about turning everyday junk into valuable products. Choose what goes in, fit your machines with relics, and see how far your setup can take you. SHRED. BUILD. CASH IN. The Shredder breaks junk into parts. The Assembler turns those parts into products. The Appraiser checks their grade and pays you in game cash. A good combination can turn an ordinary find into the best choice on the conveyor. MAKE EVERY PICK COUNT Each floor has a cash target and a limited number of items to process. A safe full of metal, a phone packed with chips, or a mysterious device: the right pick depends on the machine you've built. SAVE YOUR OVERDRIVE FOR THE RIGHT MOMENT Once per floor, push one machine harder. Shred more parts, raise your product's value, or improve your odds of a better grade. Spend the charge now, or keep it for something bigger. BUILD A MACHINE THAT WORKS YOUR WAY Collect 15 relics and try them in any of your three machines. Each machine has three slots, so every combination asks you to make a trade-off. Spend cash on an upgrade or keep it to reach the next floor's target. SMALL SCRAP. VERY BIG SCRAP. Work through 10 floors and 20 kinds of junk, from broken watches to a scrapped locomotive and an entire orbital station. When a run ends, put your unspent cash toward new relics and permanent workshop upgrades for your next attempt. • Portrait play with simple tap controls • A hands-on practice run to learn the machines • Offline single-player strategy • English and Korean • Optional reduced effects, sound and music controls • No ads, in-app purchases or account required Progress is saved on your device.
