1.0 Patch Notes!

We have been working exceedingly hard to bring you Black Mesa. Since the full release of Xen (0.9) we have done a complete overhaul pass on the combat design and guidance for all the earthbound levels, redesigned the HECU marine AI, upgraded the Vortigaunts AI, and built a new, modern user interface. At launch, well be right here to fix bugs and add quality of life improvements. After that, we will be taking a break before starting up on any big updates. So, without further delay, here is a detailed change list for Black Mesa 1.0!

Overhaul

Game-Wide

Our time in Early Access gave us lots of opportunities to beta test new content and talk with our community. We took what we learned during the development of Xen, and applied it to the Earthbound Chapters. - Improvements to every major combat arena in the game - Redesigned puzzles for clarity and intention - Enhance environments to highlight objectives

Art

We took a number of sections throughout the game and updated them visually to help the game feel more cohesive. We also made better use of the dynamic lights that we created for Xen.

Artificial Intelligence

HECU

-Better utilize cover and movement in general -Put suppressing fire on players last known location and where they expect you to be -Use grenades more strategically and more often -New environmental analysis lets them track, flank, and move in for the kill -Use weapons and abilities depending on their class -Occasionally use RPGs (grenadiers) -Use under barrel MP5 grenade launcher (commanders) -Drop med kits properly (medics) -Marines wearing a gas-mask will now use alternate, radio-filtered, deepened voice lines, which sound much more like the original HECU! -Use more voice lines and communication

Vortigaunts

The Vorts got an upgrade too, with features from their Interloper counterparts and new features to make them more fun to fight! -Dodge on spawn or dodge when player aims at Vort -Better navigate to the player -Use close-range charge attack (Dispel) -Use dynamic lights when attaching -Vorts AI now behave differently depending on how brave or scared they are feeling, which is based on damage taken / done to the enemy.

Balance

-Slightly nerfed assassins to have lower health and accuracy -Nerfed Abrams 50 cal damage to make it less murderous -Buffed Apache 30mm damage slightly

Code Fixes

-Optimized sun shadows -Optimized dynamic lights -Fixed bug with popping sun shadows -Removed view punch from smaller caliber weapons -Fixed trip mine hitbox -Added dynamic lights to portal effects -Fixed NPC teeth being black or bright colors -Made sure all tripod and ceiling turrets use tracers -Fixed gravity in Earthbound -Fixed HECU calling wrong SMG animation -All new, modern user interface -Expanded options with descriptions and performance cost
-Fixed HEV chargers giving you 76 charge instead of 75 -Fixed slide sound effect playing each time the player crouched -Changed tank machine gun accuracy for better game play

Workshop Mods Warning

Lots of mods have not been updated to work with the new version of the game. Until they are updated, they may (and probably will) cause all kinds of strange and seemingly unrelated bugs. If you want the best Black Mesa experience, make sure that you do not have any mods installed. If you have had mods in the past, it may be worth uninstalling the game, deleting all local files in Black Mesa, then reinstalling the game.

Level Design

General

-The entire game has been subject to a huge number of bug fixes and improvements throughout. The following notes wont mention every single fix, but will detail the most important ones! We scoured the community for things to fix. -Removed all old dynamic lightstyle VRAD lights and replaced them with new gbuffer dynamic lights. These will look better and perform better. -Full dynamic light pass across the whole game. Lighting should be much moodier and dynamic throughout. -Updated lightmap scales across many chapters, so baked lights will be more defined and have nicer shadows. This will result in generally nicer looking lighting. -Implemented CSM volumes across every outdoor map, which should substantially improve performance at no visual cost

Office Complex

-Fixed bad autosaves throughout -Added cover to first ceiling turret section -Added new dynamic lights to elevator -Added clip ramped steps for better player and NPC navigation -Added more dramatic lighting for the help my buddy scene where you can first get the shotgun.

Apprehension

-Overhauled opening barrel puzzle for map A to remove redundancy, better signpost the various stages of the puzzle, and encourage more exploration of the initial arena. -Overhauled lighting around the shark cage to better signpost objective. -Mood lighting across the entire chapter to enhance the ambiance and also better direct the player in multiple places. -Removed soft lock where players could put barrels in the crushers and lock progression.

Residue Processing

-Reworked navigation around the trash compactor to stall the player a bit more (gives the doors more time to open so theres less of an awkward pause), and better direct the player. -Entirely re-arted Map A opening section. -Significant streamlining across the entire chapter to reduce length of backtracking and make the path clearer and easier to discern for players. -Substantially improved performance throughout the chapter
