INSTALLATION QUICK GUIDE:

For installing mod - place decay and decay_hd folders in root Half-Life folder (for exemple: D:\Games\Steam\steamapps\common\Half-Life or etc).
The Patch version (any of them) installing only over original (2008) version.
If you use Full one - First of all you should remove previously installed version (including decay_hd folder) and only then installing newer version.
P.S. The interface may still display incorrectly if you are using a Patch version rather than the Full one (You should delete the resource folder first, and then install the Patch).

QUICK GUIDE FOR CLASSIC MODELS:

If you play on 25th anniversary update, or one of the later Legacy versions, just go to settings and find the checkbox - Enable Class Models or Enable Original Models.

If you are playing on WON version, or one of the earlier Legacy versions (which do not have a models switch option), simply copy all of the contents from decay_hd folder to decay folder with replacing (there is no mistake - decay_hd contains classic HL models).

Unexpected bit of update (19.01.2024): I had to re-upload version 1.024 due to an incorrect HD Background. I didn't want to give this update a number, besides, it doesn't affect the game in any way.

Half-Life: Decay v1.024

Major patch for fix most of the bugs, and adds some new elements.

  • Returned and updated gameui_english.txt and decay_english.txt files;

Half-Life: Decay v1.023

  • Fixed "SZ_GetSpace" error (just redirected "trigger_cdaudio");
  • The number of "Solid Entities" were reduced to an acceptable value on each map (I had to sacrifice some details to avoid an error - Too many resources on server);
  • "Protection from dumb" (v1.02) were removed (causing some troubles on dedicated server);
  • All maps were recompilled without "-extra" RAD parameter (for more authentical lightning);

  • ???

Just a detail, that hecu soldiers don't have the sounds of HD weapons (The HD M4 still sounds like the MP5 from LD). This doesn't happen with players' weapons.

could you also give back the invisible walls? like right at the start of dy_accident1 for example,after the door is opened, there should be invisible walls.

or in dy_dampen, when you crank up both the secondary dampening locks. can be very easy to fall down there and take fall damage sadly.

oh, and, if possible, I'd like to also have the PS2 training room with the small extra bit, like that intro scene with the scientists and the auto-aim practise. just for completion. would be really cool!"

Can you make a version that removes the Displacers or any other touches the mod developers added that wasn't in the original game? I saw you fixed the opening of the Hazard Course level thats good

Hey
Thank you for fixing Decay.
Question - do i need HL legacy branch or it will works with anniversary update of HL? Heard some news with mods compatibility and most of them works good with legacy than anniversary update.

This will work on the Anniversary Edition (I ran a few maps for testing).

Not sure if possible but could you swap the models, HUD sprites, and weapon sounds, so that the LD ones are in the "decay" folder and the HD ones are in the "decay_hd" folder so it isn't confusing?

Yes it is possible. No - I won't do that. Vanilla Decay, Blue Shift and Opposing Force don't have LD models, so I'll leave it as "Classic Mode".
