Sentries are automatic turrets that shoot any alien in front of them within 20 m. They fire one 5-damage bullet every 0.15 s (about 33 damage per second). They require a Robotics Factory and a powered Sentry Battery within 4 m.
Sentry Battery#
A Sentry Battery (10 team res, 25 supply) powers up to 3 sentries within 4 m. Batteries provide their own power, so they can defend rooms without a power node.
Weaknesses#
- Sentries only cover a forward arc; they turn slowly toward targets.
- Shooting through spores confuses a sentry for 8 s, and Stomp confuses it too. Confused sentries fire wildly.
- Weapon upgrades do not improve sentries.
- Each sentry uses 15 supply and each battery 25.
