Half-Life Hints
How do I reach Level D of the reactor?
1 of 7: You first need to get into the main reactor core and flood it so that you can swim up and reach one of the ladders.
2 of 7: Once you hop out of the water, you will have to deal with the electrical beams jumping off of the reactor core.
3 of 7: Whenever you need to stop and time your actions, hop on a ladder and move up about halfway. That way, you will be out of the way of the electrical beams.
4 of 7: Once you get to the top of the reactor, you will have to leapfrog from platform to platform until you get into position in front of the door.
5 of 7: Stand near the door, out of range of the rotating electrical beams, until the one hitting the door stops.
6 of 7: Run through the door and head to the right quickly. You have entered Reactor Level D.
7 of 7: Do not hesitate directly in front of the door, as the electrical beam will jump through and hit the far wall until the door automatically shuts.
