Half-Life 2: Episode One Hints
Supply Tip
1 of 2: Those power-lock doors are going to close and lock soon after you move ahead, so you should carry any portable supplies you'll want later into the room past the second power-lock door.
2 of 2: Hopper mines and explosive barrels could be useful, as could armor batteries. Most other things probably wouldn't be worth the trouble of fetching.
