You wake up with your head hurting as fuck. What just happened?.. Lights gone off for a moment, then something exploded, there was some green light… and you passed out. It was a regular work day in Black Mesa Recearch facility… that’s funny, you can’t remember clearly what your job there was. Scientist? Security guard? Janitor?

You hear alarms blaring and the message from the facility announcement system:

Military personnel, prosecute Kilo-India-Lima with extreme force.

What’s that even mean? Probably nothing good. You try to at least sit on the floor and suddenly see a two figures before you - a women in these fancy HEV-suits, gray and maroon-coloured, with a crowbars in their hands. They see you and one of them in a gray suit offers you a hand with a slight smile on her face:

“Hey, stand up if you want to live. I’m Gina Cross, that’s Colette Green and if you will follow us - you will be safe. I promise.”

Her partner checks the surroundings and suddenly makes a precise strike - hitting the brown crab-like creature with her crowbar. You hear meaty sound and her giggling:

“There you go, nasty headcrab. Come on, let’s get out of here!”
