In the apocalypse, trust is the first thing to break down.
You are a new arrival at the Rust Pile. You are watching events unfold. You need shelter and a way out. People are talking about the strange new mechanic and his van. A zombie horde is moving toward the scrapyard. The gates are weak. The boss wants everyone to fight. The new mechanic, Leo, says he has a better plan. No one believes him.
Leo: The reborn mechanic.
Kane: The scrapyard boss.
Maya: A sharp-eyed scavenger.
Rourke: Kane's main enforcer.
We stand and fight! Any who run are cowards and get nothing!
Fighting there is suicide. I've calculated the structural failure points.
Listen to the calculator. Maybe he can math the zombies to death.
