Half-Life 2 Hints
Fun Option
1 of 5: It's a real pain, but you could take all of your sentry guns along with you as you leave cell block D8.
2 of 5: There are several spots where you'd have to throw them all ahead of you with the gravity gun before you cross, starting with the "LOADING" spot that's down the corridor Alyx leads you down.
3 of 5: Any sentry guns still in the cell block will turn hostile to you when the next chapter section loads, so throw them all past the loading hotspot before crossing it.
4 of 5: Also, there are a couple of doors down the line that close permanently the moment you walk through them, so toss all sentry guns ahead of you at those points, too.
5 of 5: It can be worth all the trouble when you reach the big teleport chamber, where you can set up *eight* sentry guns if you brought all five of the previous ones along. That'll really thresh the ol' Combine!
