Technical Beta
We are excited to release our tech beta! Its the first 3 maps of the Xen chapter (which has 6 maps total), continuing Gordons adventure from the cliffhanger ending of Lambda Core. With the full Xen campaign clocking in at 19 maps, the beta is only a taste of whats to come.

The purpose of this beta is to collect bugs and feedback on a range of different computers. We have made significant improvements and changes to the Source engine, and we want the game to run as smoothly as possible. If you want to be on the bleeding edge of testing, opt into this beta. If you want the polished, complete Xen experience, you should wait. It wont be long!

How to Opt In
First right click Black Mesa in your game library. Go to Properties


Then click the BETAS tab and select public-beta from the drop down...


It will download a bunch of stuff, then you will have access to the Xen levels for the beta!

If you have not unlocked all the chapters, you will need to enable the developer console and unlock them. Go to Options, Keyboard, Advanced, Enable Developer Console. Bring up the console and type sv_unlockedchapters 19.




From there, simply click New Game, then scroll over to the Xen chapter (the chapter images were intentionally left black).



Long Jump
The beta drops you in just after Lambda Core. A big part of the last fight in LC is teaching the player how to use the long jump. If you jump straight into Xen, remember the long jump is triggered by pressing the jump button (space) twice rapidly in ANY direction. You can then use the W, A, S, D to control Gordon in the air.


Bug Reporting
We are looking for specific graphical/technical/performance bugs, especially on lower end systems. If you have any issues, please report them on our Steam forums or on the Xen-Bugs Discord channel. Please include your graphics settings and system specs or we wont be able to properly diagnose the problem.

Though our focus is performance, we are also interested in what was clear, and what wasnt for the layout and design. If you got stuck somewhere or were confused by something, let us know.

Please unsubscribe from all workshop mods if you are testing!

Discord
Our Discord is live! Please join us, hang out, and chat. Make sure to check out the server rules. The TL:DR;, its a SAFE FOR WORK server about Black Mesa, Half-Life, and Games. Please keep discussions outside those categories to other servers and have fun!

PLEASE NOTE, we have heavy server restrictions at this time. We will dial it back as soon as possible.
