Half-Life 2 Hints
How can I get to the control room?
1 of 6: Exploring the first few third-floor walkways, you'll find one that leads to two barred gates with a sentry gun behind one of them.
2 of 6: These are the gates that you need to open from the control room, so there's nothing you can do there now (except get shot up).
3 of 6: So take the path that goes through the open fence door (after sending your antlions through it to trip the laser tripmine).
4 of 6: At the table barricade, toss bugbait ahead and let the antlions finish off the soldiers before going through that area and around the corner.
5 of 6: When you can see a guard in a control room across from you, take cover in a nearby open cell and toss bugbait at the tripmined path that leads to the control room.
6 of 6: You can then get to the control room, but you'll first want to toss bugbait around the corner at the sentry gun in the closet if the antlions haven't already started attacking it.
