The Big Mech Energy Idle Wiki
You are humanity's last loyal defense AI, piloting a Mech. It auto-fights an endless stream of rogue machines. Kills drop Scrap and, rarely, Parts. You spend Scrap to level your Chassis and wire looted Parts into MechMaxxing, the power graph at the heart of the Mech, to define how you fight. Each bigger Mech is held by an AI Overlord: beat it in a duel and you can Ascend into the body it was hoarding.
It's mostly idle, it fights and progresses on its own, but active play (MechMaxxing, Full Send, Maximum Effort, drone sorties) optimizes your run.
