The rest of the maps will be available soon, and you can already listen to a full soundtrack
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 already, you’ll have to buy it for $19.99 on Steam or wait until the next sale (the game’s price was discounted to $7.99 last time).
Previously, Xen and Gonarch's Lair were available in technical beta, where they had only 3 maps. Now, players will get access to all 9 maps in these chapters.
The Crowbar Collective plans to start a beta test for the remaining chapters Interloper, Nihilanth, and Endgame in the following weeks — they’ll double the map count of the game to 18 total maps.
The developers also released Black Mesa’s full soundtrack:
For now, the full version of Black Mesa is scheduled to release before the end of this summer. The game originally hit Steam Early Access on May 5, 2015.
