You wake up with your head hurting as hell. 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 figure before you - a woman in one of these fancy HEV-suits, maroon-coloured, with a crowbar in her hand. She sees you and offers you a hand:

“Hey, stand up if you want to live. I’m Colette Green and if you will follow me - your ass will be saved. Probably.”
