Snippet of the back of the Half-Life (PS2) box

Half-Life: Decay is an co-op expansion included in the PlayStation 2 port of Half-Life, developed by Gearbox Software.

Like Gearbox's other expansions 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 Dr. Gordon Freeman, Dr. Gina Cross and Dr. Colette Green. Dr. Gina Cross is the model for the Hazard Course hologram, and can be seen in Blue Shift when viewing one of the security camera footage. Dr. Green is a new character created for Decay.

Half-Life: Decay can be played in singleplayer (allowing player to switch between Gina Cross and Colette Green), and multiplayer, with another player controlling Colette Green using the second controller.

Although Gearbox completed a PC port of the game, Decay was never released "due to powers beyond Gearbox's control". As such most Half-Life players never got a chance to play through it. Decay is also not available through Valve's Steam service. There was a fan-made port of Decay, released on 23rd September 2008 for Windows.

Gearbox note on Decay

I work for Gearbox and did most of the coding for the Decay work we did on the PS2. First I'd like to say that there is no interest or desire on our part to fox this project. Everyone here thinks it would be great to see this ported to Source. We even had a port of the game ready on HL1 for the PC, but due to powers beyond our control, were unable to release it at the time. So it's always been of interest to us to see Decay make it to the PC since, as someone else here has mentioned, it does deliver a part of the Half-Life storyline so it's always been a shame to prevent a large portion of the Half-Life players out there from seeing that part of the story. When this mod is done I will probably fire it up with a friend of mine that never had the chance to play Half-Life on the PS2. It's been a while since I played through Decay (though I certainly played through it quite a bit while we were working on it).
