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. For the last 15% we want to not only recreate it, but improve upon it to make it an enjoyable and memorable experience. We feel it will take us considerable time to get the last 15% up to our standards, and putting a time estimate on it would be a total guess.”

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 10 hours of single player campaign. Multiplayer deathmatch and team deathmatch with 6 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.”

Surface Tension Update - Patch 2

Note: This update does not contain Xen! We are hard at work on Xen. This is a small stability update aimed at lower-end users.

  • Fixed a number of potential crashing issues on low-end graphics cards.
  • Fixed an issue with the depth buffer that was causing the game to crash for some users.
  • Fixed some instances of the "Disable CSM" option not working properly.
  • CSM/depth buffer will now be disabled completely by default on low-end graphics cards that are not officially supported.
  • Fixed mat_hdr_level & mat_tonemapping_occlusion_use_stencil convars not working properly. This will hopefully help to resolve a sporadic issue for some users where the game would turn dark after a few seconds. If your game turns dark after a few seconds, try setting mat_tonemapping_occlusion_use_stencil to 1 in the console.

Perfect remake of HL1.

It's great to play this game having played the orginal so long ago. The graphics are more than ok and it runs very smooth. Also 21:9 and FOV support is great. This game feels finished with no real bugs or issues. There are some changes to the original but in a good way. For anyone who has not played HL1 i would really recommend this. Even today so many years later it's still a very good game.

Black Mesa Review

  • Atmosphere
  • Weapons
  • Small extra details
  • The original Half-Life feeling
  • Graphics
  • Music
  • Secrets
  • Overall gameplay
  • Loyal to the original Half-Life
  • Mods and custom maps
  • Enhanced experience

  • Early Access, missing Xen
  • Movement
  • Basic Source engine problems
  • Minor performance issues

Black Mesa is one of the best remakes ever made. It keeps the same feeling of Half-Life, but still makes it completely new experience. Even tho the game is missing Xen it is in a good place. The devs work hard will bring us Xen one day way better than it was. Black Mesa does justice to the Half-Life series.

Xen was promised to be comming later for those who purchased. Now Xen will be a stand-alone game, which we'll have to purchase seperately.

Asshats got a little taste of that steam money, and decided they wanted more.

This a fantastic remake of the original HL.
I recommend playing Half-Life before playing this game as you will be engulfed by the nostalgia of the 2000's and will be impressed on how things have changed over the time span of 10 years.
Unfortunately, Zen, an important story arc in Half-life is still being developed and has yet to be released.

I finished the non steam version couple of days ago and although it used inferior version of source engine and had bad optimization on some places with lots of bugs, it was still amazing! And I'm sure the steam version could only get better.

I must say I never got the excitement from some parts of the original Half-Life because the graphics engine of it's time was not capable of creating certain kind of atmosphere. With this HD remake I felt like I was rediscovering the original gem as it was meant to be!

Long story short, If you liked Half-Life then you'll love Black Mesa now!

Right so when this was first released about two years ago I saw a lot of people complaining that it was janky, broken and unimmersive, but they failed to see the main part of this games description, early access. Yes of course it's gonna be broken and coming across as though it's unfinished because it is, now however after millions of updates where all the tweaks and implementations that Crowbar Collective have put in the came is well polished and gorgeous, Xen still isn't ready for play but maybe they're doing what I suspect most would do and that's recreate the entire level, for what it is though it's wonderful, the weapons and punchy, cathartic and fun to use, any imbalance in the enemies has been removed, and the gameplay is smooth and enjoyable, think of this as what the new Doom is, an awesome game from the nineties remade and remastered with modern tech and is still just as awesome.

Basically Half Life 1 with amazing graphics, clear narrative and smooth gunplay.

Not a complete storyline. (Game ends before the final chapter of HL1)

Clean and open environments.

Interesting and variable enemies.

Seemless and immersive platforming (Never though I'd say that)

Source engine <3

If your a person who loves Half-life like me, and wants to play a game about Half-life and doesin't want to play Half-life with 1999 graphics, then this game is for you! This is a very fun game with good graphics and will satisfy any Half-life lover.

This game is Half Life as it was always meant to be seen and played, but our computers couldn't handle it in the 90s. Black Mesa incorperates all the best that the Source engine has to offer; it's drop-dead gorgeous in the graphics department and the developers deserve a huge round of applause for all the work they must have put into this.

At the same time, I should point out that it's not exactly the same game as the original Half Life. In the original I always thought it was intended to be comical how the dumb looking scientists kept getting killed left and right or blindly blundering into danger only to be splattered into half a dozen pieces. Black Mesa on the other hand borrows a lot of the darker and sometimes tragic atmosphere of the HL2 games. The scientists feel more like real people trying to survive a disaster now, and you feel bad when they die, rather than thinking it's part of a joke. I think that level of immersion though makes the game that much more of a triumph.

The gameplay is much more sophisticated now as well. I remember in the original one of my favorite tricks was to hide behind a box and wait for Vortigaunts to turn the corner before blasting them with the shotgun; I can't do that now because Black Mesa made them too smart for that. Nevertheless, that makes the gameplay more chalanging, more realistic, and therefore more fun.

I only have one real complaint about the game and it's that the bullsquids' eyes are on the tops of their heads instead of on the sides like in the original HL, but that's just a little detail only a nerd like me would take notice of.

At the time I'm writing this, they still haven't finished the Xen levels of the game but it's absolutely worth buying as it stands right now. Whether you're a hard-core HL fan like me, or you've never heard of it before, if you like FPS games, this one's an absolute treat.

If you want to play the original Half-Life with better graphics, sounds, models etc and don't want to get Half-Life: Source? This mod is definitely for you.

Also, the music is excellent.

Black Mesa does all the things that Half Life did so amazingly just as well.
It also makes all the not so good things about Half Life really good.
That makes Black Mesa my defacto favourite game of all time.
