1. Build a junk machine

Four parts: a body (hull + health), wheels (speed + grip), a weapon, and a boost. Paper is a glass cannon. Metal is a rolling brick. Ceramic hits like a truck until it shatters. Legendary bottle rockets don't roll — they fly. W / S climb and dive, Space afterburns.

2. Drive it in the arena

Side-view crash arena. Each wave is a different place — playground, kitchen, cafeteria, rooftop, freezer, the dump. A / D to roll. W / S to fly on rockets. SPACE to boost. Weapons still fire themselves. Rubber bands, staples, and ice cubes track flyers. Hits send machines tumbling. Wheels and weapons can get knocked clean off. Hunt the Ice Cube (freezes them solid) and the Fire Extinguisher (foam-blasts flyers out of the sky).

3. Durability is the whole game

Paper cup = almost no hull. Bottle-cap wheels = zippy and drunk. A fork stabs. Rubber bands let a sippy-cup snipe a thermos.

4. Mystery boxes

You do not buy parts. Spend scrap on mystery boxes and pray. Duplicates refund scrap. Hunt the Power Saw.

5. Boosts

Bolt on a soda for nitro, a cookie sheet for a shield bubble, glue so parts stay on, a magnet to yank them in. Last machine still moving wins.

WINNER!
