The Radar Tower is a level 1 special tower that both the CORE and the ARM can build; it has no attack of its own, but can detect enemy units within its coverage even in unexplored areas and display them on the minimap. Enemies that are detected by radar but are not seen visually will be displayed as "unidentified onjects", and any unit that can attack them must be manually ordered to do so unless a Targeting Facility is built.
The Radar Tower detects the location of enemy units at long range. All of the radar information is displayed on the mini-map.
The Radar Tower contains a set of sensors for locating enemy units. It can detect (but not identify) the enemy at long range. All the radar information from each unit is organized and displayed on the mini-map.
