The Sensor Tower is the physical embodiment of Atriox's watchful presence in every Outpost. It is through the Sensor Tower that the Banished assess the local battlefield and detect nearby cloaked units. Additional Sensor Towers extends the cloak detection range and view of the Outpost's surrounding area. Sensor Towers occupy a Turret slot.
Atriox's agents are ever-alert for schism and disloyalty, and his chosen keep watch on the Banished battlenet for discordant voices, but it is through the sensor tower network that the Banished maintain hyper-awareness of the battlefield.
