External Sensor Pod is a technology that can be researched at the War Center in Tech Level 3. It costs 200 Food and 100 Nova, and gives Mechs, Ships, Command Centers, Fortresses, and Turrets +1 attack, range, and line of sight. Elevation Tracking must be researched before it becomes available, and External Sensor Pod is a requirement for Targeting Sensor.
Like Elevation Tracking, this technology will make the player's Ships, Mechs, and defensive structures more dangerous, and is vital to ensure proper base defenses.
"At Tech Level 3, all units and structures bolstered with Elevation Tracking technology may be similarly enhanced one step further by means of External Sensor Pod research."
