Half-Life Hints

How can I best handle the assassins in Hazardous Materials Bay A?

  • 1 of 16: Very carefully, and with various weapons.
  • 2 of 16: After you go through the door that enters the bay, move straight forward cautiously.
  • 3 of 16: Move past a big red box and one of the two light gray pillars.
  • 4 of 16: Have your crossbow ready and check to the right.
  • 5 of 16: Your first assassin to assassinate is just to the left of a tall red box stack that you can see while standing in between the two light gray pillars.
  • 6 of 16: Turn the sniper scope on and edge slowly in crouch mode to the left until you can see the assassin's leg, then shoot it. One dart should do it, even on Difficult level.
  • 7 of 16: Moving along your original straight-from-the-door path, you should soon see some red boxes up ahead past lots of green boxes. Shoot the explosive barrels that are right next to the red boxes to kill your next assassin target. (Use the hornet gun's secondary attack mode; there's no point in wasting any ammo on this.)
  • 8 of 16: Those were the two easy ones. Now things get a little harder.
  • 9 of 16: Go back to the two light gray pillars you were near before and ready the hornet gun.
  • 10 of 16: Move between the pillars, turn around, and inch backwards, looking up at the little green walkway that's up high.
  • 11 of 16: An assassin is standing on that walkway, and she will see you if you try to get into position to sneak-shoot her with the crossbow. You can make her move without seeing you by hitting her with a few hornets (aim at the bottom of the green walkway for best results) and then deal with her later.
  • 12 of 16: Now go across the room to where two more little gray pillars are and start bashing all the boxes that are blocking access to the stairs.
  • 13 of 16: A nearby assassin will hear you and come partway down the stairs. After all the boxes are bashed, you can ready the crossbow and sneak-shoot her in the head without her seeing you if you're careful.
  • 14 of 16: You may then have to deal with the assassin you stirred up with your hornets earlier. If so, do, then go up the stairs and across the room on the green walkway.
  • 15 of 16: On the other side, you'll be home-free if you had to kill a second assassin on the stairs. Otherwise, there'll be one near the stairs on the other side to deal with now.
  • 16 of 16: Once she's down, the place is yours. Be sure to hit the health and armor stations at the bottom of the second set of stairs before progressing onwards (via a little lift in one corner on the upper level).
