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

Hello. Thank you for making this mod! I'm a huge fan :)

Could you please upload the language package files? All mirrors I found on the internet are broken...

Hey,

I prepared an installation and running guide for GNU/Linux. Enjoy! ;-)

I partially managed the mod to run on GNU/Linux by copying hl.so from /Half-Life/valve/dlls to /Half-Life/decay/dlls and adding gamedll_linux "dlls/hl.so" line to liblist.gam in /Half-Life/decay. However the game rejects to join any internet servers. When I try to play the game as single player, it starts but fails to load second player and NPCs, unable to switch between players; so it is not possible to proceed. The mod/game needs some sort of decay.so to function on Linux properly.

i know it's probably a pain to do, but could you make a version where you don't have to keep switching players?

Could have added barney's AI to co-star (shoot and follow), while he was not being controlled
