Modder ‘Aynekko’ has released a new major update for one of the best total conversion mods for Half-Life, Diffusion. Diffusion is a mod that aims to push the Half-Life engine to its limits. So, let’s see what its new update brings to the table.
Diffusion 1.1 comes with new voiceovers. It appears that previously, the mod had AI voices. But now, as the modder stated, the entire voiceover has been replaced with human-recorded lines. This should please a lot of people who don’t like any AI stuff in their games and mods.
Patch 1.1 also brings balance tweaks to weapons, as well as improvements to the enemy AI. For instance, there was an oversight where the enemies tended to pick only one tactic most of the time. This has been fixed. A few enemy encounters have also been redesigned, and more enemies have been added in some places too. As such, the game may now be a little harder. Still, I believe this will be good news for most die-hard FPS fans.
It’s also worth noting that the modder has added new 3D models for some scientists, as well as new decals and some new prop models. Bunnyhopping is disabled by default, but you can enable it by using sv_enablebunnyhopping 1. The vehicle camera can now be rotated in 1st-person mode. In 3rd-person, you can adjust camera distance using the mouse scroll.
In total, Patch 1.1 brings over 100 tweaks, fixes, and changes. You can download its latest version from here. You can also find on that page its complete changelog. From what I could see, the modder has not shared a new trailer. Thus, at the end of the article, you can find an older trailer for it.
Finally, you can install Diffusion into your Steam folder as a Half-Life mod. All you have to do is download the mod, and put the main Diffusion folder into …\Steam\steamapps\common\Half-Life. Restart Steam, and you should now see Diffusion in your library.
Speaking of the first Half-Life game, there are some other cool mods that you can download for it. For instance, you can download Brutal Half-Life. Then we have a mod that adds Full Ray Tracing/Path Tracing to it. This is a must for everyone who wants to re-experience the main game, so be sure to download it.
Now, if you don’t want Path Tracing, you can use this AI-enhanced HD Texture Pack. This pack will overhaul all of the game’s textures. However, its lighting won’t change in any way. Thus, you’ll get an experience closer to the vanilla game.
Halo: GoldSource is a fan-made game that brings Halo’s gameplay into the Half-Life engine. It has two main modes: Slayer and Firefight. You’ll find lots of classic Halo maps and some new ones made just for Firefight. Plus, you can use many cool Halo weapons.
Finally, we have Half-Life: Delta. Half-Life: Delta is a Total Conversion Mod, featuring 4 chapters and 31 gameplay maps. Oh, and there is a new Aliens-based TC Mod, called Solitary Echoes.
Have fun!
