Bay 12: Mech Repair casts you as a technician who repairs massive war machines while a conflict unfolds outside your hangar. The game features industrial-style mechs similar to those in MechWarrior, built like tanks on hydraulic legs with cockpits full of switches and displays.
Damaged mechs arrive in steady procession. You diagnose problems using scan data and pilot reports, then use welders, drills, and spanners to fix them. Pilots like Lieutenant Iona Vale report specific issues, such as "left leg hesitation after extended operation" at higher temperatures. The game does not clarify whether incorrect diagnoses can shape the war's outcome.
The repair loop follows familiar job sim structure. You scavenge broken parts for components, earn credits from completed work orders, and must split earnings between restocking inventory and buying tools. You can also remove rust and apply new paint jobs to mechs.
