The guards do not care at all what happens to the prisoners. At all. Prisoners fight and kill each other all the time. Guards do nothing. Prisoners can come and go out the west gate so I'm not even sure what those guards are there for. Four guards guard the main gate. One guard with a dog patrols a small area of the camp. At least half the prisoners are out of sight of guards at all times. You can spend tons of time out of sight of guards.
And yet step outside the camp for a few seconds and somehow all guards know you escaped. It's not that the collars are tracking devices, because you can have free reign of the restricted areas in the fort and no one goes to stop you, and no one goes to track you down outside the fort either.
Well, it would be interesting if source callers WERE tracking beacons somehow, though in that case it would be immediately obvious if you disabled one. I guess the logic of the guards not caring all that much about the prisoners is that there's no way to escape from the island except through the swamp, so who cares what the prisoners do as long as they don't go that way. Though then again logically a prisoner could easily swim around the fort, so that's a bit silly.
It would be nice to have some explanation for how the guards would know you'd escaped though, or remove the auto-hostile from that. Would be awesome if they had some kind of tall watchtower where they could see all escape routes, and you'd be warned about that watchtower. However, if you climbed the watchtower and killed the guard (maybe a mini-boss) without being seen otherwise, maybe you could escape without drawing attention.
