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 1

Note: This update does not contain Xen. We are working on Xen! This is a small hotfix patch to resolve some of the issues with the Surface Tension Update.

Programming
  • CSM should now be functional and working correctly on AMD cards.
  • French and Portugese translation/captions are added and fixed in the main menu.
  • Fixed a bug where disabling CSM would cause it to set to “very low” when you next start the game.
  • Potentially fixed the “CSM ghosting” bug where a weird overlay would appear on the screen if you enabled CSM.
  • Fixed a bug where the godrays option would reset when the game is restarted.
  • cl_autoweaponswitch cvar added to disable automatic weapon switching, if needed.

Level Design

C2A5G (Surface Tension Uncut)
  • Fixed a bug where if you backpedal through the door that leads to the car park at the beginning of the map, it would close and could not be reopened again.
  • Fixed invulnerable AGrunt at the helipad if the player tries to save the Osprey.
  • Fixed alternate vent route Headcrabs from clipping with the player and being invisible if they the player jumps over the vent gap.
  • Fixed various conditions that allowed the player to exit via the bomb trap room and get into the TOW courtyard that way.
  • Add player clips to prevent exploitation of the map.

C2A5H (Surface Tension Uncut)
  • Fixed a bug where the hangar Guard choreography would get broken if you went to the hangar door exit before reaching the part of the level where you actually meet the Guard.
  • Corrected hanger security door to use the correct sounds like the rest of the doors in the map.
  • Player clipped the dumpster by the jump pad to prevent the player from getting stuck.
  • Removed the fence behind the guard shack to prevent the player getting stuck.
  • Ladders on the fire escape now work in case the player decides to use the jump pad to get on them.
  • Fixed 50Cal getting tank projectiles stuck in it.
  • Add player clips to prevent exploitation of the map.

Multiplayer
  • Fixed a bug where sv_ranked would crash servers on startup.
  • Generated loading screens for dm_crossfire, dm_rail, dm_power and dm_chopper. All official maps should now have proper loading screens at all resolutions.
  • Added some graphical detail to a few areas in dm_rail as well as a playerclipping pass to make projectiles get caught less on silly obstacles.
  • Fixed c2a5h and c2a5i showing up on the multiplayer map list.

Miscellaneous/Notes
  • Several big community mods have been broken with the last update. If you see missing textures or any strange behaviour, those are likely the cause. On a Rail Uncut is also broken and will cause texture errors in a few places in the game, particularly On a Rail. The author is working on fixing these issues.

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

Pros:
Remakes Half-Life with improved level design, textures to rival Half-Life 2, and new dialogue and sounds.
Cons:
Soundtrack doesn't always fit with the tone of the game, too much rock in some areas. This isn't DooM but it feels like it with the music on.
Multiplayer is dead.

After following this mod for many years and then buying it on steam and holding on to it without playing for a year I finally did it. Hoping that XEN comes out soon I went ahead and played through it. This game is phenomenal! I congradulate all the people working on this game as it is a masterpiece. Some of the areas that I hated in the original game were incredibly fun in this version. Maybe Valve should give funding to these guys to develope Half Life 3 and stop torturing people as they have been doing for over a decade. I am speechless on how good this game is. I am a huge fan of the half life series and played them through all of them many times over.

Awsome game and really well polished for an early access title. This is most definately a faithful remake of Half-Life compared to Half-Life: Source. There has been some changes to gameplay and level design that add an extra layer of challenge so it doesn't seem too easy. This game plays a lot like Half-Life 2 and running on the Source engine it looks kinda dated but the level of detail in the environment is enough to make it nice to look at. Especially with the CSM shadows although they seem to have artifacting like the weapon not rendering the shadows correctly when looking up or down. The voice acting is good but not great (certainly an improvement over the original Half-Life). The music is kick ♥♥♥ with an intense soundtrack playing when first reaching the surface while soldiers are firing at you and bombs going off around you. Please be aware that this game is not without its bugs like the NPCs going back in forth when they don't have anymore targets to attack or if I fire my weapon at a scientist he would just stand there not reacting. The multiplayer is solid and plays more like the original Half-Life. Everything is there but with limited character customization and some bugs like the text being scrambled up for some odd reason or the player's animation getting glitchy while standing around sometimes. This game seems more like a solid title rather than early access and even back in 2012 this was an early access game worth of its title. This game is a must play for the fans of Half-Life and worth checking out if you are new to the series.

You play as Mrogan Freeman in the worlds most unsecure secure facility known as Black Mesa. Relive your childhood meories of being killed by marines that claim they are saving you and shooting innocent guards for ammo in this explosive action packed shooter. This fantastic 3/4 of a game is a must have for any lover of crabs (the ones on your head not the ones on your balls) and old school shooter mechanics like health pickups and breaking every crate you see. This balls to the walls shooter is worth of being in evry persons steam library

Awesome remake for Half-Life 1. By playing Black Mesa it has brought back many good memories of when I played Half Life 1 when I was a kid. This is the same great atmosphere and gameplay as Half-Life but better graphics and also the new update added 3 new levels to the game. 10/10 would crowbar again.

The definitive upgrade. Eight years (and counting) in development, this love-child of Half-Life fan community, the god of remakes, outmatched all our expectations of how would Half-Life look in Source Engine. It takes everything, every little detail, from the original and extrapolates something, which is almost always true and kicking ♥♥♥. It polishes and mutates the immortal HL design with surgical precision. You will have no trouble playing through this, because this is what Half-Life looks like in your dreams. Especially the beginning shows us how important Half-Life was for development of narrative in computer games. This isn't a mod but a full-fledged game and I wouldn't be surprised if many of its developers started working for Valve. It doesn't even matter it doesn't have a proper ending, the 10-hour experience is well enough to sate you. Now what I didn't quite like is the soundtrack. I don't think that rock guitars should be overused in mysterious sci-fi. :) The genius of HL OST is hard to surpass. Also, the Source Engine has gone a long way since Half-Life 2 and the devs improved it a ton, so don't expect to run it as smoothly as HL2 on older hw on highest details, especially in the newly updated outdoors chapters.

I just replayed BM again after the ST Uncut update. I have played this so many times, from the mod till now. Personally the best way to experience the Half Life universe. Worth every cent as is, even without Zen. If you like Half Life, support these devs and get it. The recent ST Uncut update is proof that they will complete this project.

The game it sel is good. Graphics are without a doubt on par with today's standards.
only problem is that they're are certainly bugs, one of them i seem to get alot is that sometimes the ai/npc don;t react or move or do anything. they just kinda stand where they spawn. but then again, you can fix this by loading an older save or at worst loading a new game with the same chapter. gets kinda annoying for this happens to me a bit often. but then again, this is early acces, so hopefully this bug will be fixed when this game is released.
do i still recommend this?
it's a great game

this is one of the best remakes out there. MP is also very funny, better than most deathmatch/TDM games. It needs more players tho, but when Xen is released, im sure that playerbase will grow and more people will buy it.

its worth the $20, buy it. you wont regret it.

Don't buy this game at the current time, devolpment is VERY VERY slow,
Yes I enjoyed game, as far one of my fav mods, but the devs are slow, not responding to us about Xen, they said in 2015 it'll be availaple in early 2016, and not yet, not here, so no.
A bit disapointed that I have to write this :c
