Beta Version of Chapters Xen and Gonarch's Lair in Black Mesa Will Be Available on August 1
The full game is expected to release very soon
Check out the Black Mesa: Xen trailer below:
It was also revealed that the remaining levels — Interloper, Nihilanth, and Endgame — will be available for public test in the coming weeks.
You have to own a copy of Black Mesa to participate in the beta. If you don’t have the game on your Steam account already, you’re in luck — the game is currently on sale for $7.99.
The Crowbar Collective said that the fans have already helped them to fix most of the game’s known bugs. Because of that, they believe that open beta is the best way to polish new chapters before their release.
If everything goes according to plan, the full version of Black Mesa will be released before the end of this summer. The game originally hit Steam Early Access on May 5, 2015.
