*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!”
