Valve might finally be working on Half-Life 3, according to a Half-Life expert and a recent credit in an actor's resume.

Over the weekend, Half-Life fans spotted a now-removed credit on a voice actress's resume that marked, "Project White Sands (video game)," and speculated that it could be referencing a new Half-Life game. This is due to the resume directly mentioning that it was a project with Valve, and also that "White Sands" is a park and missile range in New Mexico. Protagonist Gordon Freeman's former employer, Black Mesa, is located in the New Mexico desert.

Now, Valve expert Tyler McVicker has created a video explaining why he thinks Project White Sands could be the next fully fledged non-VR Half-Life game. He reported that another single-player Half-Life game was in pre-production around the same time as Half-Life: Alyx, and the codename was HLX.
