Story:Half-Life: Decay is an expansion pack for Valve Software's science fiction, first-person shooter video game Half-Life. Developed by Gearbox Software and published by Sierra Entertainment, Decay was released as part of the PlayStation 2 version of Half-Life. It is the third expansion pack for Half-Life, and like its predecessors, Decay returns to the setting and timeline of the original story, albeit portraying the story from the viewpoint of a different set of protagonists: two scientists working in the Black Mesa Research Facility. Decay is a cooperative multiplayer game, designed to be played by two people working together to pass through the game's levels. In September 2008, a group of Ukrainian developers unofficially ported the game to Windows as a modification of the PC version of Half-Life.Show more

This game and story is officially locked on the Playstation 2. It is a 2 player co-op entry in the Half-Life series. There is a fanmade mod that ports this to PC. While it does work (mostly), it is not easy to get it set up for multi-player, which is pretty much required to play the game the way it was meant to be played. It's similar to "A Way Out" and "It Takes Two", but good luck finding someone to play it all the way through with the clunky mods. An official re-release running on a newer engine with online player match-matching would be fantastic treat for Half-Life fans who want more official content and have never been able to experience this story which is part of the canon.
This cant be bought anywhere.

The gameplay consists of two primary modes: Mission and Mother Base. Mission are the actual action sequences of the game where the player must infiltrate an enemy territory or fight a boss, whereas Mother Base is an army management. Some changes have been made to the standard Metal Gear formula: the player is now unable to move or shoot while laying down and while pinned to a wall, making Peace Walker the first game since Metal Gear to lack any crawling ability.
