Half-Life Hints

I have made it to the reactor core on Level B. Now what can I do?

  • 1 of 9: The reactor core is being used to generate teleportation portals.
  • 2 of 9: The reactor core in Level B is broken down into 3 subdivisions.
  • 3 of 9: Each level of the reactor has one portal and three "ports" into the portal.
  • 4 of 9: Each port will transport you to a different place, but only one of the ports per subdivision will allow you to progress further, rather than dropping you off in some dead-end.
  • 5 of 9: The idea is to figure out how to use the portals to get deeper into the level. This requires that you "climb" the reactor using portals until you reach the top of the reactor, where one of the ports will take you further into the Lambda complex.
  • 6 of 9: Read on if you would like to know exactly what each portal does.
  • 7 of 9: Start by jumping into the portal by the Level B Core entrance.
  • 8 of 9: The exit portal for the initial portal is right in front of the first subdivision of the reactor core.
  • 9 of 9: You need to time your entrance into the initial portal so that you pop out the exit portal directly above one of the rotating platforms.
