Half-Life 2 Hints
How can I get that set up?
1 of 9: Get a knocked-over sentry gun from nearby and drop it inside the guard room.
2 of 9: NOTE: If you have trouble getting a sentry gun all the way up the stairs due to invisible force fields, try taking it partway up and then lifting or throwing it over the railing.
3 of 9: Send your antlions out of the room and quickly block the stairs leading into it with the large desk and all the green cabinets that are in the room.
4 of 9: This is to prevent the antlions from coming in and knocking over your sentry gun after you get it set up. Remember that they can't follow you any further, anyway.
5 of 9: Use the gravity gun to get the sentry gun set upright, then put it so that it's facing out through the broken window.
6 of 9: You'll need to put it just left of the window hole so you can get through the hole without knocking it over.
7 of 9: Go through the window hole quickly so as not to get shot, then drop down to the floor below and run for the exit.
8 of 9: When you're safe, wait and listen as the antlion guard is periodically shot by the sentry gun.
9 of 9: If there's a long time with no sentry gun fire, move up next to the exit doorway so the antlion guard will see you and move around a bit (unless he's dead).
