*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.”
