Sentry drone

Sentry drones are a type of hostile drone from the Odyssey DLC that can be found in ancient ruins. They will patrol the halls of the ruins and attack colonists if spotted.

Occurrence[edit]

Sentry drones spawn on specific quest sites belonging to the Hostile Ancients faction. Those quests are either gravship-related or given by the orbital scanner:

Frozen terraformer (gravship quest)
Ancient reactor (gravship quest)
Abandoned orbital platform (gravship quest)
Abandoned Platform (orbital scanner quest)
Orbital Satellite (orbital scanner quest)

The number of drones spawned is on a curve based on the number of threat points, with the ancient reactor and orbital satellite quests spawning more drones than the other quest sites at higher threat point levels.

Drones spawned per threat points (TP)
Quest	Location	Origin	100 TP	1000 TP	5000 TP
Frozen terraformer	planet	gravship	2	8	16
Ancient reactor	planet	gravship	2	10	20
Abandoned orbital platform	orbit	gravship	2	8	16
Abandoned Platform	orbit	scanner	2	8	16
Orbital satellite	orbit	scanner	2	10	20

Sentry drones cannot be constructed or controlled by players, unlike hunter drones and most mechanoids.

Summary[edit]

Drones are similar to mechanoids in several ways - they avoid cover, do not drop equipment when destroyed, die when downed, and have 100% toxic environnment resistance and 100% vacuum resistance. Unlike mechs they are not totally immune to flame and heat damage, but are non-flammable and can open doors, even player owned doors. This has been confirmed by the developers as intentional.

When generated as part of a map, drones will be at least 200 years old^[Verify]

Psychic sensitivity of 0%.

Dead sentry drones may be shredded at a machining table or crafting spot for 15 steel, though these values are affected by mechanoid shredding efficiency^[Verify] as well as any missing parts on the drone.

Combat[edit]

Sentry drones are always equipped with a scattergun, which they do not drop upon death. See the scattergun page for further information.

Sentry drones have a shooting accuracy of 96%, equivalent to a pawn with a Shooting skill of 8. They have a melee hit chance of ?%,^{[Detail needed]} equivalent to a pawn with a Melee skill of ?.^{[Detail needed]}

Analysis[edit]

Past the early game, sentry drones are not a dangerous threat on their own. Their scattergun is a worse pump shotgun. In close quarters, they can easily be engaged in melee. In the open, they are easy to kite due to their short range and being slower than humans. Also, they always appear in quest sites - where threats are scaled down to compensate for traveling - meaning that if bringing an entire colony via gravship they are unlikely to pose a serious threat.

Sentry drones still pose some threat to pawns, as they can serve as distractions for hunter drones and other types of drones.
