Half-Life Hints
Why won't this security guard let me pass?
1 of 4: There are two security guards who are blocking entrance to certain areas in the complex.
2 of 4: One will not let you pass no matter what. He is standing directly in front of an airlock and specifically tells you that you cannot pass.
3 of 4: The other stands next to a retinal scanner. If you try to go through the doors, he will explain what you need to get through.
4 of 4: You will need to be wearing your HEV Suit. The guard cannot let you pass until you are properly prepared for the experiment.
