Vault Drills: Breach the Vault Door on Big Con and Aggressive
Without drills, Big Con and Aggressive cannot open the vault. The prep itself is short — hit a construction or industrial site, steal two drills, deliver them. Combine this with the Power Drills optional prep and you spend significantly less time at the vault door, which translates directly to more loot inside.
