The Radar Spire is an essential structure for the Epsilon Army, which grants access to more advanced technologies and provides radar for the proselyte.
Radar Spires provide Epsilon commanders with the radar mini-map and clearance to use more potent technology. Additionally, it provides the use of genetically modified Ravens that function as advanced scouting units.

While the Radar Spire no longer functions as a Psychic Sensor like its counterpart in the original game does, it becomes more important than ever to build a Radar Spire as Epsilon Tier 2 requires both this building and the Pandora Hub to be completely unlocked. In addition, both structures are required to build Pandora Hub plugins, which unlock Tier 3.
If the player opts for an infantry-oriented or aircraft-oriented strategy, and/or simply gain a tactical advantage in the form of radar and reconnaissance powers, building the Radar Spire first before the Pandora Hub should be preferred.
Other than granting access to a portion of Epsilon Tier 2, the Radar Spire also provides access to the following support powers:
|A controllable, genetically modified Raven can be summoned anywhere to survey the battlefield. Scout Raven has no cost but takes 4:00 to recharge.|
|Epsilon proselytes can temporarily gain insight on enemy activity within a certain area with the Vision support power, that functions similarly to the Mind Reader. Vision has no cost but takes 6:00 to recharge.|
- In Awake and Alive, the destruction of Radar Spires can prevent Epsilon from sending more reinforcement.
- Radar Spire first appears as a buildable structure in Memory Dealer.
- In Hysteria, the first objective is to capture a Radar Spire. After that, all the Bio Reactors on the map will be revealed.
- In Relentless, the capture of 3 Radar Spires is the primary objective of the mission, as these buildings contain data that leads to the discovery of Yuri's main stronghold. All 3 Radar Spires are invulnerable.
- In Insomnia, a Dybbuk Hive could be destroyed by destroying the Mind Readers and Radar Spires on a path distinguished by reddish pavement connected to the Hive.
- In Tainted Empire, capturing 2 Radar Spires is the main goal of the mission, similar to the case in Relentless. The intelligence acquired from these two structures reveals Yuri's next operation. These 2 Radar Spires are also invulnerable.
- In the Ascension Challenge, 4 Radar Spires in the upper center of the map can be destroyed to reset the timer of the arrival of the Golden Armada. However, each Radar Spire is guarded by an Aerial Fortress Irkalla and several base defenses. Radar Spires built by the AI will not reset the timer.
