Seeker Drones are weapons for the Saucer.
Seeker drones launch missiles that home in on targets. They can destroy ground targets, and lock-on and take down airborne targets like helicopters, Nexo saucers, etc. The manual describes them as angry hornets. They are bright and presumably plasma/electricity or other energy-based weapons.
- Upgrades mainly include the number of missiles that can be fired simutaneously, ammo capacity and damage.
