Black Mesa, previously known as Black Mesa: Source, is a fan-made remake of the original Half-Life. The ultimate goal of the mod is to recreate the original Half-Life from the ground up, using the advanced capabilities of the Source engine to create a new and more engrossing in-game world with more varied, complex environments and more challenging, realistic gameplay.

Originally requiring Source SDK 2007, Black Mesa is now considered standalone and now available at Steam for only $19.99. The original release date for the project was set for 2009, but was delayed for 3 years. On the 1st of September, 2012, the project leader Carlos Montero (cman2k) had announced that Black Mesa will be released in 12 days [1] and posted a countdown on the official website. [2]

Overview Edit


The Anti-Mass Spectrometer.

Black Mesa, whose development began in November 2004, was born of the discontent fans experienced when playing Half-Life: Source; when considering the living environment Valve created with Half-Life 2 using the Source engine, the original game fell far short of what many players thought could be done with the software, basically being a straight port, except for improved water and lighting effects along with the inclusion of ragdoll physics. According to the developers, "Black Mesa: Source was built and founded on the principle that Half-Life: Source did not do the original title enough credit... [Black Mesa] set out to reconstruct the original title, giving it new environments, models, and abilities."

Black Mesa features original textures, models, sounds, voice acting, and music (composed and produced by the mod's sound designer, Joel Nielsen) designed specifically for the mod. However the developers intend to preserve all of the gameplay elements from the original game, without adding entirely new enemies, weapons, or levels. The game uses Half-Life 2 models with custom textures, such as the crowbar, the Colt Python, the Headcrab, the Barnacle, and the crow.[3]

Since development began, the team has released many images, including in-game screenshots of most chapters and multiplayer maps, model renders, concept art, as well as several gameplay videos and trailers and excerpts from the soundtrack.

Most likely due to the amount of publicity given to an unofficial third-party mod, Valve Corporation privately asked the producers of the mod to remove the "Source" part from the title to avoid confusion on whether it is an official Valve product or not.

The developers released a teaser trailer in early 2007, and a full-length preview trailer in late 2008. They have also released images, videos, and concept art during the project's development. Black Mesa was given an official release date of "late 2009" in the spring of 2009, but this date has since been changed to "when it's done", after the development team was unable to fulfill this date.

After almost 8 years of development, the mod was released on September 14, 2012, although it is only playable up to the Lambda Core. Xen and the later chapters were excluded due to being unfinished at the time and slated for a release at some point in the future. As of September 11th, 2012, Black Mesa was accepted into the Steam Greenlight service with the next release to include the missing Xen chapters and possibly also the Deathmatch multilayer segment. The developers stated this version of the game would be a paid-for version but that the free version would still be available.

In May 2015, Black Mesa was released as a Steam Early Access, however it still does not include the Xen chapters but does include Deathmatch multiplayer mode. The old 2012 version however won't be updated anymore due to technical and time constraints.

Community ModificationsEdit

This is an abbreviated list of notable mods created for Black Mesa

  • A remake of Half-Life: Uplink was created by community member Hezus, and can be played as "Chapter 0".
  • A remake of the Hazard Course is currently in development by a small team of community members.
  • TextFAMGUY1 created two extensive map packs called "On a Rail Uncut" and "Surface Tension Uncut" that seamlessly add areas from Half-Life that were cut by the Black Mesa team.
  • .RK created two small expansions, the "'On a Rail' - Loop Mod" and "'We've Got Hostiles!' - Vent Mod" that adds in small parts of Half-Life cut from Black Mesa. The "Loop Mod" is fully compatible with the aforementioned "On a Rail Uncut".


  • Gordon Freeman - Like the original, he is the main protagonist and playable character.
  • Eli Vance - Eli appears in the chapter Anomalous Materials and in the next chapter Unforeseen Consequences. He is in the role of the unnamed black scientist who checked out the broken equipment and later let Gordon Freeman through the door, telling him to get help, in the original Half-Life, who was retconned as Eli Vance and revealed in Half-Life 2.
  • Isaac Kleiner - Like Eli, he appears in the chapters Anomalous Materials and Unforeseen Consequences. He is one of the three scientists who Gordon meets up when heading to the test chamber, and also one of the two scientists checking out the broken equipment with Eli Vance. In Unforeseen Consequences, he replaces the Einstein scientist who is sitting on the floor in shock being comforted by Eli Vance in the original Half-Life. When a headcrab spawns nearby in one of the containers, which Kleiner inspects, he is fascinated by it.
  • Wallace Breen - Although he doesn't appear, just like the original Half-Life, he is still indirectly mentioned by scientists as the "administrator." In an easter egg, a paper on a cork board reveals Wallace Breen's plans to take over the world, including making friends with aliens and building a giant towering headquarters, something he pretty much does in Half-Life 2. Moreover, a security guard can trick Gordon into thinking the "administrator" is right behind him.
  • Barney Calhoun - He "appears" in the Black Mesa Inbound Chapter like the original Half-Life, trying to get access through the door. However, the developers decided not to disclose that this particular security guard is Barney in order to not conflict with the narratives between the original Half-Life and its expansion pack Half-Life: Blue Shift, but they still made a nod to the expansion pack by portraying the guard as missing his equipment and making the player unable to see his face in normal gameplay.
  • The G-Man - Like his original appearances in the Half-Life games, he observes the player from a distance and always disappears. His appearances are pretty much the same as in the original Half-Life with some tweaks. He appears in the level Questionable Ethics, where he did not appear in the original Half-Life.

Other small characters seen in Half-Life 2 are possibly also seen. For example, the headcrab Kleiner inspects seems to be Lamarr.

Like the original Half-Life, it includes groups of scientists and security guards that Gordon comes across during his path, although all the models have more varieties. Some of the scientists and guards have names of their own revealed through dialogue. HECU Marines again appear (including medics that were not present in the original game), as well as the Black Ops assassins (now wearing what appears to be black Advanced Knee Replacements or Long Fall Boots from the Portal series). Unlike in Half-Life, where all guards only carry a Glock 17, some guards are equipped with the Colt Python and Shotgun which boost some effectiveness against enemies (although security guards armed with the shotgun are not very effective as they are immobile while using it).

Detail from one of Black Mesa's computer models. Microsoft Outlook and Mozilla Firefox can both be seen on the desktop, and the desktop's start button (bottom left) reveals that it is running Windows XP.

  • Examining the desktops shown on the computers in the Office Levels show that they are running Windows XP. This is anachronistic, as the original Half-Life and Black Mesa are both set at some point in the late 1990s.
