A Corporate Safe is a mainframe device containing credits or, occasionally, an item. Some Corporate Safes are taller, and contain more loot than other safes. When a safe is hacked or rebooting, it can be looted by an agent on an adjacent tile.
Every typical facility has five Corporate Safes, except when a different number is chosen as a custom difficulty setting. Corporate Safes do not occur at all in OMNI facilities.
