The popular Half-Life Fan Remake, Black Mesa, is finally releasing the last zone in the game: The Xen. Well, they released a teaser, at least.

If you’re a fan of Half-Life, you probably have heard about Black Mesa. It began as a mod for the Source 2 engine, porting the 1998 first-person shooter Half-Life into a more modern format. The project gained popularity and was eventually accepted by Valve themselves, releasing as its own game on Steam in 2015 under Crowbar Interactive.

The game has been in active development since. One of the most notable missing features was the existence of the final world, the Xen. Instead, the game ended right at the moment of teleportation to the alien environment.

Now the developers have released a new teaser trailer dedicated to their implementation of the Xen.

The reveal was in commemoration of the 20th anniversary of the original Half-Life’s release, November 19, 1998. Before this, the developers had only shown concept art for the Xen. They also note that the area isn’t ready yet, but they’re targeting for a release in Q2 of 2019.

You can find it for $20 on Steam now, if you don’t want to wait. I’m just glad to finally see the giant testicle crab in HD.
