There’s pretty much no question that Valve’s 1998 FPS game Half-Life is one of the greatest titles ever released. A masterful blend of storytelling, action, adventure, and game-changing mechanics, it was a revolution whose impacts are still being felt to this day. So it’s no surprise that a group of fans are rebuilding the game from the ground up so that its visuals match its timeless gameplay.

Dubbed Black Mesa, the fan-made reimagining features, “all-new soundtrack, voice acting, choreography and dialogue” that is built upon, “new visuals, new voice over, updated gameplay encounters, stability changes and more.” Already released on Steam as an Early Access title, the game’s climactic final chapter that takes place on the alien planet of Xen hasn’t been a part of Black Mesa but has been promised when ready. Now, the first look at what that world will look like has been released in the above trailer, which showcases Xen in ways that have never before been seen.

The planned release date is the second quarter of 2019, so it’s still a little ways off. But for those who have been playing Half-Life since it came out, a few months will pass by in a flash.
