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. 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  and posted a countdown on the official website. 
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. Some Half-Life 2 models were used with custom textures, such as the crowbar, the Headcrab, the Barnacle, and the crow.
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 multiplayer 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 did not include the Xen chapters but did include Deathmatch multiplayer mode. The old 2012 version however won't be updated anymore due to technical and time constraints.
In November 2018, an update containing Xen was announced on the occasion of the 20th anniversary of Half-Life, given an official release date of 2019. The first part of the chapter Xen was released on June 25th, 2019 as part of a technical beta. The rest of the chapter Xen, along with Gonarch's Lair, became available on August 2nd, and the first part of Interloper was released on October 1st. The final chapters of the storyline were eventually released on December 7th. The whole Xen segment was largely expanded and improved in comparison to the original game as it was to have platforms look like a living ecosystem. .
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 created by PSR Digital was released in December of 2015. It is only compatible with the mod version; the Early Access version is yet to be released, due to technical problems with Black Mesa's Steam Workshop. This remake features the entire voice cast of Black Mesa.
- 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. TextFAMGUY1 later joined the team to work on multiplayer maps, with a heavily updated "Surface Tension Uncut" eventually being integrated into the main game's public beta in 2016 and "On A Rail Uncut" was added to the game's Steam Workshop.
- .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 that Kleiner inspects could 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 (which were exclusive to Opposing Force); the latter will heal wounded Marines as long as Gordon is at some distance away from them, and now they wield the same primary weapons (MP5/SPAS-12) as the regular soldiers. In the mod version, HECU Marines were always heard communicating with loud voices via radio, like in Half-Life. However, the Steam version has replaced most of their chatter, and the soldiers now speak with an unfiltered voice during normal circumstances, similarly to Opposing Force, and sound much more human than before. In rare occasions, some HECU soldiers can be seen using RPGs before switching to their standard MP5, likely substituting the M202A1 FLASH that is absent from Black Mesa.
Black Ops assassins also return, now wearing what appear to be black Advanced Knee Replacements or Long Fall Boots from the Portal series. They also wield dual Glock 17 pistols (as opposed to a single one like the original game), and while they don't have visible suppressors, their firing sounds are quieter than normal. Unlike in Half-Life, where security guards only carry Glock 17s, some guards are equipped with the Colt Python and SPAS-12 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).
The Xen creatures are roughly the same as the original Half-Life. However, in the chapters set in Xen, there are some new variations of existing creatures:
- HEV Zombies, or ZEVs - Zombified scientists wearing HEV Suits; their suits emit distorted voices, and when a Zombie is killed, the "beep" sound for an HEV user's death is heard.
- It should also be noted that the part set on Earth features zombified security guards and zombified HECU soldiers, both of which were only present in Opposing Force.
- Explosive Houndeyes - Red glowing Houndeyes that explode when attacking the player or when shot with a single bullet.
- Knockback Houndeyes - Tougher version of the original Houndeye; their sonic attacks heavily knock the player to the back and/or upwards rather than dealing direct damage.
- Beneathicles - Underwater Barnacles attached upside down at the bottom of the water.
While in Xen, all Vortigaunts in the chapter "Interloper" are docile towards Gordon. This behavior, understandably a rebellion against the Nihilanth, was carried over from the original game, where this was only the case at one instance. Early in the chapter, an Alien Grunt is seen beating up a Vortigaunt to the ground while another Grunt keeps an eye on the other frightened Vortigaunts, until Gordon intervenes. While they do not assist Freeman in direct combat, the Vortigaunts will help him in a few tasks, such as disabling some force fields that were blocking his path. However, Alien Controllers will sometimes appear, and will force them to attack Gordon; the Vortigaunts become friendly again once the Controllers are killed. It should also be noted that Alien Grunts are more agile in Xen than they were on Earth, being able to strafe faster and jump towards elevated surfaces.
Weapons and equipment
The same handheld weapons from Half-Life appear, remodeled, although the behavior of some of them has been modified. For example, the MP5 has a realistic 30-round magazine and less reserve ammunition than before, but deals higher damage, is more accurate, and fires M203 grenades faster. Another example is that the Crossbow deals extremely high damage (being capable of killing an Alien Grunt with one hit in the torso, even in Hard mode), at the expense of a very low fire rate and much less bolts in reserve. Mounted weapons such as the Browning M2 are usable again.
Like in Half-Life 2, the player is able to pick up certain objects, often required in order to progress through the game. Flares can sometimes be picked up, allowing Gordon to set enemies on fire, most notably early in the game when he hasn't picked up the crowbar yet.
The Long Jump Module is now equipped with landing jets, negating fall damage while progressing through Xen.
There are some devices in Xen (like Healing Showers) that will restore not only the player's health, but their armor as well. Additionally, some devices in the chapter "Interloper" have the ability to refill the depleted uranium ammunition for the Tau Cannon and the Gluon Gun; these devices can be used for an unlimited amount of times.

The tracks with a "pre-2019" note next to them were only played in older versions of the game, prior to the Xen updates in 2019. Additionally, while "Resonance" plays in a part set on Earth, Joel Nielsen's OST lists it among the Xen tracks, as it was released alongside them. There are a few tracks that don't have proper names; in this case, the names found in the game files (such as "Mscl_Ambience1" and "xen-ride0") are used in this list.

- Examining the desktops shown on the computers in the office levels show that they are running Windows XP. This is accurate, as the original Half-Life and Black Mesa are both set at some time in the 2000s.
- Many have noted that despite his Doctorate, Gordon Freeman's job at Black Mesa is largely experimental, consisting mostly of manual labor. Black Mesa seems to make address this in Anomalous Materials, where two nameless scientists can be heard discussing how management has been forcing Ph.D's to perform functionary work.
- The game includes a lot of nods and Easter eggs pertaining to the Half-Life mythology, as well as questions and debates raised by fans on certain issues in the series.
- A guard makes reference to Freeman cutting off his ponytail. In most concept art and promotional photos, Freeman has a ponytail (and even has one on his original Half-Life model) although in some photos it is completely absent.
- A scientist in the locker room talks about the HEV suit and how it has a detachable helmet. In some concept art and promotional photos, Freeman is seen with a helmet, which is absent in his original in-game model, as well as most other photos depicting the character. This has caused debate to fans whether or not Freeman is wearing his helmet at all during the original game.
While the official website is the main source for most official images, all personal websites of the respective team members also provide further, exclusive images.
Note that many of these images show pre-release models, or models that are only in the mod version.
