Sentry intrusion countermeasure

Sentry intrusion countermeasures are hostile digital entities in DiMA's memories during Best Left Forgotten

Background
These sentries exist in DiMA's memories, which can be accessed using a terminal in the Nucleus Command Center during the quest Best Left Forgotten. In order to retrieve the memories, paths need to be built for the indexers by moving blocks, while the sentry intrusion countermeasures attempt to attack them, preventing their progress.

Gameplay
Round in shape and able to hover above the constructs of the simulation, the sentries utilize lasers to destroy the indexers.

Appearances
Sentry intrusion countermeasures appear only in the Fallout 4 add-on Far Harbor.
