A Router.

A Router which has been hacked.

A Router which has been looted and permanently disabled.

Routers are a security measure which appear in some FTM facilities at mission difficulty 3 and higher. While a Router is active, it adds 1 firewall to a random mainframe device at the start of each turn, except the first turn of the mission. Routers are found in the Contingency Plan DLC.

Routers are mainframe devices which can be hacked, or disabled temporarily by rebooting them. A hacked or rebooting Router can be looted to acquire a Valuable Tech item, after which the Router becomes permanently disabled.

Routers provide soft cover, allowing agents to hide on adjacent tiles.
