Description

Black Mesa is a remake of the game Half-Life and built on the updated engine Source, which allowed to improve the texture, model, and graphics in general. If you, like many, are a fan of Half-Life, then we recommend downloading this modification, which should give you new impressions of old motifs. Half-Life is undoubtedly one of the best games ever created, and its new breath in the modification of Black Mesa is sure to please many. To maintain the spirit of the cult game, almost everything remains as before (plot, weapons and missions), there are only significant graphics improvements, and you are waiting for new sound effects and a new soundtrack.

Installation Guide

Step-by-step setup process for CODEX

  1. Open the .iso with a virtual drive program (e.g. Daemon Tools) — on Windows 10/11 a double click mounts it on its own.

  2. Install the game by running setup.exe and following the wizard.

  3. After installation, copy the entire contents of the CODEX folder from the disc into the game folder and agree to replace the files.

  4. Start the game through its usual shortcut, preferably as administrator.

    Gonarch and Bebcrab AI ChangesGonarch AI now behaves differently and deploys different attack patterns based on Easy/Normal/Hard difficulty.Fixed bug causing Gonarch to do 250 damage on melee attacksFixed bug causing Gonarch to spawn 60 bebcrabs instead of 15 in lower arena battleGonarch shove damage in map B chase reduced by 50%Gonarch shove damage in map C chase reduced by 70%Gonarch shove view punch and knock back amount greatly reducedGonarch AI tweaks for final lair arena battle.Fixed a crash related to Gonarch mortarsFixed a loophole where Gonarch could die/gib in map A and final upper arena Fixed Gonarch physics throw attack not respecting cool-down system under certain conditionsMinor Adjustments to chase AI to make it more forgiving, reduce melee attack damage, and scale based on game difficulty settingBebcrab jump height reduced to 20 units high, making it much less likely they clip one of your rocketsBebcrab damage reduced by 50%Bebcrab max count in final upper arena reduced by 33%New UI Fixes / ChangesIf you are interested in testing the work in progress UI, use -newgameui as a launch command.Fixed major performance drop when using new UISingleplayer game is now paused when UI or Console is ActivatedBrought up default Qt behavior for key Auto-RepeatGame Console: Command Input now has historyGame Console: Partial Autocomplete implementation (WIP, expect bugs)Game Console: Log Area now 1-2% faster than old UIAdded \"Enable Developer Console” to the Game options screenAdvanced Settings Menu is now fully hooked upKnown IssuesBebcrabs can still be tracked by RPG. We are testing changes to have them not track/collide with RPG rockets. We think the change in jump height has addressed most, if not all of the problem. Let us know what you think!Columns in the final fight arena still kill the player in 1 hit. This will be fixed in a future level update.It is still possible to get the Gonarch stuck in certain areas of the level. We are testing level fixes to address this.
