In the morning inside the Advanced Biological Research Lab in Black Mesa Research Facility, near Section G's Hydro-Electric Dam. As you're the construction worker who through the facility complex and entering the containment room and you're looking an Xenian soldier or simply known as Alien Grunt, are captured in container tube as he trying to beating thin glass until he's unable to get out. You then saw a red button inside the glass, you draw out your hammer then slamming into it and press the button. The alarm has raised when he's finally breaking the glass, he jump out of the container as he stomps towards you, sizing you up. His orange eyes tear through you, before raising his Hivehand and preparing to attack.
