Half-Life 2: Episode One Hints
Section 1: Getting Back into the Citadel (ep1_citadel_00)
1 of 11: After Alyx and Gordon are rescued by phantom Vortigaunts (much to the G-Man's chagrin), you'll find yourself being excavated from some rubble by Dog.
2 of 11: When Dog holds out his hand with the gravity gun in it, move forward to take it. It's back to being its old pre-Citadel self, but it's still a *very* useful tool/weapon.
3 of 11: After Alyx points out the Citadel's fiery top and talks a bit, she'll hear her father's voice on a nearby comm unit and will climb a tall bit of rubble to get to it.
4 of 11: As Alyx talks to her father on the comm unit, look just to the left of it to find a couple of health packs that you can heal up with.
5 of 11: After the conversation is over, Dog will politely lift the backside of a wrecked gunship that's blocking the path. After Alyx goes through, crouch-walk after her.
6 of 11: You'll then come to a rather severe drop, and will have to find some way to continue on to the end of the ridge Alyx mentions.
10 of 11: From where you exit the van, head down the nearby corridor that has a small fire on the floor near a big hole. As you go that way, part of the ceiling explodes.
