Half-Life 2 Hints
Sentry Gun Tips
1 of 6: You could try peeking through the doorway just long enough to toss some bugbait down that way, but you may have to wait awhile for the antlions to knock over the sentry guns.
2 of 6: There are also the usual possibilities of throwing grenades and/or large items with the gravity gun, or crouch-walking toward the sentries while holding a large desk (available nearby) ahead of you.
3 of 6: But the best way in this case is to run through the doorway and into a side room on the right where the sentries can't shoot you.
4 of 6: Then, while they're firing on your antlion followers, move through the side room until you get to where you can hit the sentry guns with regular-fire gravity gun bursts through an open doorway that's next to them.
5 of 6: However, watch out for the laser tripmine that's set across that doorway.
6 of 6: You'll want to knock the sentries over, then go back the way you came and use bugbait to trick an antlion into triggering that tripmine for you.
