but if you read the loading screens, is states that sentry bots use cores for there power source. You can actually steal them when they are in cool down mode. Unless they are getting mr. handys to change out there cores, there would be no functioning sentry bots after 200 years. unless cores lasted that long. But one lasts about a day game time with constant running around in PA

i have never had anyone take mine, either. But then again, i have never had a settlement get attacked. 92 hours played

Hmmmm. Nice defensive addition.

This might sound mean, but your friend must be stupid, who would do that?
