Sentry Towers are Tier 2 Units that players will have access to after completing the "Longbow Tower" and "Turret" Research in the "Strategic Traps" and "Wall Traps" Research Category respectively, along with a Lv.10 Academy. Like all other Traps, Sentry Towers help defend the player's Empire from enemy invasions. These specific traps are fairly fast and cheap to produce, and are primarily useful in defending against Tier 1 or Tier 2 Ranged troops.

- Cheap to Build, especially in large numbers.
