Half-Life 2: Episode One Hints
Okay, how can I get to this one's power box?
1 of 13: As usual, look around for an alternate means of leaving the area you're in since the door can't be opened yet.
2 of 13: There's a vent shaft opening down at floor level a ways left of the door, right near where you found the hopper.
3 of 13: Soon after you turn right in the shaft, you'll find a small opening on the right with some rungs on one wall. Skip it and go straight unless you want some armor batteries.
4 of 13: When you turn a corner and see that the shaft ahead has an opening at its end, stop there and quicksave your game.
5 of 13: If you proceed forward, a chunk of the shaft will break off and fall, taking you with it. Worse yet, the room you fall into is full of laser tripmines and explosive barrels!
12 of 13: Go along the shaft until you reach a weak-looking grating that's covering an opening in the shaft floor. Looking down through it, you'll see that yet another room full of explosives awaits you below.
13 of 13: That room happens to be the one with the power box and the power-lock doors, so use the power box to open the doors and get Alyx to rejoin you.
