The objective of the Tower is to climb on its top, using Super Jump and Super Sprint, and activate it. There are usually some warp points The Protagonist can activate and teleport there if they have fallen down.
All Towers are marked as Target on the Map. In order to start Diversion, the first warp point must be activated. After this, next warp point will be marked on Map. After activating all warp points, you need to climb on top of the Tower. If you have fallen down, there is a marker in the bottom, which will teleport the player to the last warp point. If you have climbed on top, press Action button to activate the Tower. The player will be awarded some Cache and XP. There are also a lot of Clusters which may be collected to upgrade Super Powers.
This diversion can be completed before obtaining Super Powers and without activating the warp points. Use of a small helicopter, like the Thompson found at the airport or in the dry dock in Salander, is needed to fly to the top. All Clusters located all over the tower can still be collected afterwards.
The only tower which doesn't have fixed vehicle spawns nearby is the Stanfield tower. There is a parking lot near the bottom, with many randomly spawning vehicles, but no known unique spawns.
