Black Mesa is a fan-made remake of Half-Life utilizing the Source engine as a standalone game. All key areas and events of the original game have been recreated faithfully, however there are a number of changes and tweaks that allow this game to be called re-imagining rather than a remake. These differences include: multiple changes to the maps - some have been altered and expanded, while others (including on-rail levels) were considerably shortened; new voice overs recorded for all the characters with many new dialogue lines added; the number of unique NPCs has been increased considerably; HEV suit's flashlight battery is now infinite; enemy's AI and weapon damage have been tweaked; a new weapon (flare) has been added; achievements have been introduced etc.

The version released in September 2012 contains 14 chapters of the original Half-Life, excluding the last several chapters that take place in the alien dimension Xen. It is now considered a Legacy release, being replaced by Black Mesa on Steam. This version is still available via the official website, it just no longer receives updates.

The game was in development for eight years and the team had to move from the original Source engine available in 2004 to the later version released in 2007. The game was originally developed as a modification, but the eventually released version does not require any other game to run - the player just needs to download and install the Source SDK Base 2007 package which is distributed by Valve Corporation for free.
