Half-Life 2: Episode One Hints
How can I get safely down this dangerous hallway?
1 of 14: In the main game, you often had to toss explosives at sentry guns in order to knock them over before you could traverse their hallways safely.
2 of 14: If you save your game and then run down to their end of the hall, you'll see that they're positioned in cases behind metal bars so that they can't be knocked over.
3 of 14: So tossing hoppers or other explosives at them is useless. You'd better find a way to move from cover to cover until you can get to their end of the hall and figure something out.
4 of 14: After the zombies at your end of the hall are all dead, run across the sentries' hallway entrance and get to where you can pull in the nearest hopper mine without getting shot.
5 of 14: Run it back across to the other side of the hallway entrance and drop it for later use. Also, pull over the loose door and small green file cabinet that are over there for use as projectiles.
6 of 14: TIP: If you'd moved fast enough when you first entered this area, you could have caught the hopper that detected a zombie near it and hopped at it, thereby saving it for your projectile stockpile.
7 of 14: Now run into the hallway, taking cover behind the wall protrusion on the left wall that's just before the side doorway.
8 of 14: This will provoke a bunch of zombies into coming out of that doorway.
9 of 14: After all the zombies are dead, run back to the wall protrusion that's near the left-side doorway, and then quickly run around it and through the doorway.
10 of 14: That will prompt zombies to come pouring out of the doorway that's in the wall on the other side of the hall a bit farther down.
14 of 14: Thankfully, dropping the force field also closes the doors on the two sentry gun containers, so all you have to do now is find and reset any hostile hoppers that are left.
