01
98 NAR Regional
Patrols the road north of Whitespring near the cargo train — the most reliable spawn. Beware the Annihilator variant; it can one-shot a mid-level character, so come geared.
Sentry BotSpawn Locations
Tracking a Sentry Bot in Appalachia? The Archive logs 3 spawn locations for it across Savage Divide and The Mire. Server population and active events shift the odds, but these are the spots the field notes keep returning to.
02
Dyer Chemical
Sentry Bots patrol the grounds as groundskeepers. If one is missing it was killed by a rampaging enemy — server-hop and it returns.
03
Nuclear Silos
Each silo interior holds Sentry Bots — convenient if you are already running Alpha, Bravo, or Charlie for nuke codes. The Critical Hit a Sentry Bot challenge wants a VATS crit; cripple-arm dailies reset with a server-hop.
