Half-Life: Decay is an add-on included in the PlayStation 2 port of the first-person shooter computer game Half-Life, developed by Gearbox Software and published in October of 2001, now being remade by independend Ukrainian developers for PC with the help of other european developers/fans.

Our team is working on straight port of this game to PC! "Decay PC"'s active development began in mid-October of 2005 and release is scheduled to be somewhere in Summer of 2008.

Like Gearbox's other expansion packs Opposing Force and Blue Shift, Decay returns to the setting and timeline of the original story, but with different player characters: two female colleagues of Gordon Freeman, Dr. Gina Cross and Dr. Colette Green, who both take part in the Anomalous Materials laboratory experiment - they make preparations for the experiment under the Test Chamber such as monitoring Anti-Mass spectrometer and delivering anomalous materials to Dr. Freeman. When disaster happens both women together with their collegues Dr. Rosenberg and Dr. Keller try to save personell of the facility and reverse the resonance cascade to seal the dimensional rift.

For more information please visit official site of the project.

Non-public beta version of the project was realesed dec. 31, 2007

This needs a 2023 update. Half-Life was recently updated.

Yeah, sorry, but considering the fact that the last post made by the developers of this mod (which was made on the official website that doesn't exist anymore) was made back in 2011, I don't think this mod is going to be updated anymore.

Well technically, it does, but the menu is kind of messed up.

By that do you mean stuff like the text in the options menu being messed up? If so there is an easy fix:
1) Go to where your Half-Life directory is and from there go to valve/resource. Copy the file that's called gameui_english.txt.
2) Back from the root of your Half-Life directory, this time go to decay/resource and erase the gameui_english.txt file that's already there. Now paste the other gameui_english.txt that you copied before here.
3) While still in the decay/resource directory, open the new gameui_english.txt file if you want to make slight changes that were in the original file. Find the line that defines GameUI_GameMenu_CreateServer and on that same line replace "Create server" with "Play Decay". Similarly, find the line that defines GameUI_CreateServer and on that same line replace "Create Server" with "Choose Mission...".
