Advanced Radar Tower
The Advanced Radar Tower is a level 3 special tower available to both the CORE and the ARM; it is basically an upgraded Radar Tower with twice as much coverage, giving it the largest radius out of any radar unit. The extended detection the unit provides can help long range units such as long range plasma cannons seek out distance targets, as well as observe huge areas for enemy movement.
Like the Radar Tower, the Adv. Radar Tower can be used to notify the player of any oncoming enemy attackers via the minimap so they can prepare a counterattacking force, with the extended range granting the player additional time for preparation. Another use for the Adv. Radar Towers is to plan an attack on the enemy using the locations of enemy units it provides through the minimap in combination with what terrain has been unveiled through scouting and knowledge of what units are at certain locations, something the T1 Radar Tower doesn't do particularly well at due to the shorter range requiring the player to build them closer to enemy territory, thus reducing the risk to enemy units wanting to safely destroy it before other towers can be built to protect it.
Adv. Radar Towers have the same problems as other radar units, the most notable being the inability to detect foes if they under the protection of a jammer unit, with other problems including the inability to detect units that are fully submerged and being unable to uncloak units that are within the radius of a unit's stealth ability.
