Granby, Colorado. 2003.
The dozer didn't sell at auction. Nobody wanted it. Now it sits in your workshop. You have a grudge, a welding torch, and thirty-five thousand dollars.
PHASE 1 — THE WORKSHOP
A man alone in a garage at 2am.
Spend on armor, engine, cooling, treads, cameras. Every upgrade draws suspicion. Every day costs cash. The neighbor peers over the fence. The hardware clerk asks too many questions. An inspector heard the welding. A reporter's been asking about your zoning dispute.
You cannot afford everything. Every run is a conversation about what to sacrifice.
PHASE 2 — THE RECKONING
Drive. Destroy. Survive.
Six priority targets. One machine. Six thousand kilograms of concrete and steel on tank treads. Ram buildings at speed — heavier armor and stronger engines turn walls into dust. Heat builds as you demolish. Overheat, and the engine stalls for three long seconds while the sirens close in.
Every choice you made in the workshop plays out here. The cooling you skipped. The cameras you couldn't afford. The armor that's keeping you alive.

A NOTE ON THE SOURCE
This game is a work of fiction inspired by a real event. On June 4, 2004, Marvin Heemeyer drove a modified Komatsu D355A through Granby, Colorado. No one else was killed. The grievances, the machine, and the man were real.
Project Haymaker is not about celebrating what he did. It's about understanding how someone gets there — and handing the wrench to the player.
