In order to establish control of the skies in Gotham City, the Arkham Knight has the meat of his militia stationed at several watchtowers dotted about the city. Batman can optionally take down these watchtowers by defeating all of his guardians and using Explosive Gel to destroy the security console.
Even more watchtowers are established when Deathstroke takes over, and beating the mission has no specific outcome other than crippling the Militia's forces.
- The name is a reference to the term Occupy movement, a public protest of social equality.
- The watchtower of Elliot Memorial Hospital is considered one of the hardest scenes in the game, due to the high amount of Combat Experts, Brutes and Stun-Sticks.
