What the developers have to say:

Why Early Access?

“Making a game with the scope and scale of Black Mesa is a massive undertaking. Back in 2012 we made the decision to release what we had completed up to that point, and were blown away by the community’s response, feedback, and improvements to our work. We want to keep that relationship alive and well by using Early Access as a tool for allowing our community to participate in the final phase of Black Mesa’s development.

In addition, our ambitions go beyond the original Xen chapters found in Half-Life. We have a standard of quality that we have to achieve. Early Access allows us to commit resources to bring you the remaining chapters with the quality that you expect.”

Approximately how long will this game be in Early Access?

“We currently have the first ~85% of our single player campaign completed (8-12 hours). For the last 15% we want to not only recreate it, but improve upon it to make it an enjoyable and memorable experience.

We are targeting a summer 2017 release for the Xen chapters.”

How is the full version planned to differ from the Early Access version?

“The conclusion of the single player campaign, with the addition of the Xen chapters
Final polish on the Earth-based chapters of the single player campaign
More multiplayer maps
More multiplayer gameplay modes”

What is the current state of the Early Access version?

“Over 8-12 hours of single player campaign. Multiplayer deathmatch and team deathmatch with 8 completely re-imagined Half-Life 1 maps on the Source Engine.”

Will the game be priced differently during and after Early Access?

“Black Mesa will be $19.99 USD during the Early Access phase. This price will not change after we move out of Early Access.”

How are you planning on involving the Community in your development process?

“We intend to work closely with our community as we complete the final portions of Black Mesa. We started out as a modding team aiming to do true justice to a Half-Life: Source port, and we won’t forget our roots.

The Black Mesa game hub and forums will be the primary points of interaction with our users. Many team members regularly browse these areas to discuss ideas with the community, and to show progress on game development. Community feedback will be sorted into groups and taken into account as we develop.

We also support Steam Workshop, and will be watching and encouraging developments there.”

Source Engine Security Fix



We recently became aware of an exploit that allows remote code execution via Source multiplayer. We patched the current build of the game to protect our players. More information about it here:

Summer Media Update



Happy summer all! We hope that everyone is having a great start to their summer. To celebrate, we proudly present to you our first public screenshots of a Xen exterior. All running real-time, in- game, with no edits.



Unfortunately, as some of you may have already predicted, we are going to need to push back our planned release of Xen to later this year, in December. We know that this is not what anyone would want to hear, but after taking a long and hard look at what we want to achieve, we have decided that this is for the best. We do not want to compromise on Xen’s quality in any way. That said, we consider December to be a do-or-die deadline.

To soften the blow of the bad news, here are some additional tidbits and updates regarding what we have done for Xen so far.

Example of the Level of Detail We Are Going For


Interloper Map B Scale


New Dynamic Light System
As part of our continued efforts to bring Xen’s graphics up to the best possible standard that they can be, we have upgraded Source to a new deferred rendering system that supports fully dynamic lights! These new “next-gen” lights cast real-time light, shadows and god rays. These won’t replace all the lights in the game, but we can use them in many special cases where we want the lights to be particularly gorgeous. These lights are much better optimized than other Source implementations of dynamic lights, and are more robust.

Not only will this new lighting system help crank parts of the the game up to 11 in terms of graphical fidelity, these will also be powerful tools for modders as well!

Color Correction
We’ve started a color correction pass for the whole game. The goal is to better unify the game’s visual style and to add full screen effects during the more intense sections. Most of these effects will be quite subtle, but here is a more noticeable example.


Weapon Holds
We fixed the soldiers holding the weapons wrong. It took some serious animation trickery to retarget the bones on top of the existing Half-Life 2 animation library, but it worked well once we figured it out. No more hands clipping through the guns!


Thanks as always to you guys, our wonderful community, for your support! As always, we will continue to work at full speed on Xen, and we hope to have more updates, information and media for you guys soon.

Reviews

“This is Half-Life updated just enough to make it palatable for contemporary tastes, but not so much as to deviate from the original vision.”
YES – Kotaku

“Black Mesa Source winds up being exactly what it always promised to be – a modernised, faithful recreation of a deservedly landmark first-person shooter.”
Rock Paper Shotgun

“It's a brilliant tribute to one of the greatest videogames ever made, and it's also a good game in its own right.”
8/10 – Destructoid
