Half-Life 2 Hints
Explosive Barrel Tip
1 of 6: Before you cause those cops to appear by approaching the dead end, set up an explosive trap for them.
2 of 6: Carry the two explosive barrels that are in the second wrecked building across the tracks.
3 of 6: Put one of them a bit to the right of the unopenable blue door, and the other one at the corner that's a ways to the left of that door.
4 of 6: NOTE: If the first one is too close to the blue door, blowing it up will also blow up the second one. You don't want that.
5 of 6: Hit each barrel once with the crowbar to "prime" them, then go back across the tracks.
6 of 6: After you get to the dead end area, you can hit the barrel to the right of the door with two quick pistol bullets to kill the first cop that appears, then do the same with the other barrel to kill the second one when he rounds the corner.
