Vault Hardening

Defense pieceData updated 2026-09-19

How to get it

Stack laser doors, turrets, and Legendary guards on the vault corridor.

  1. Map the shortest path from map edge to your vault.
  2. Fill that path with walls → laser → turret → Legendary.
  3. Keep a partner near the vault during Double Cash / KotH chaos.
  4. Rebuild immediately after a successful enemy crack.

Overview

End-state defense for the cash you already earned. Upper-floor AFK farm only works if the vault corridor holds while you are upstairs.
