A website connected to the Half-Life fan remake is currently displaying a mysterious countdown.

Pictured below, the timer on BMRF.us (that's Black Mesa Research Facility), is overlaid on top of a modified Emergency Broadcast System template. It occasionally flashes images of one Half-Life's most elusive characters, the G-Man. Only static can be heard.The countdown should reach zero on Tuesday, May 5 at 7:47am PT. Accounting for time zones, this lines up with 8:47am in New Mexico, which is the geographic location of Half-Life's Black Mesa Research Facility.It's also the time you hear when you first step onto the train at the beginning of the game.Craig Mirfin, a level designer on Black Mesa Source, tweeted "Soo many channels but nothing on?? https://www.blackmesasource.com/ #gamedev ," followed by "They're waiting for you gordon in the test chamberrrrr https://www.bmrf.us/ ?"Could this all be a creative prelude to a final Steam release date for Black Mesa Source? We're reaching out to the developers and we'll let you know when we learn more.If you're unfamiliar with Black Mesa Source, a group of developers overhauled the original Half-Life in the Source engine, complete with new music, voice acting, and more. When they released the game in 2012, it included a good chunk of the story, but stopped before any of the later Xen levels.
