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, and has now been released as a mod for PC by independent Ukrainian developers along with the help of other European developers/fans.
The team has created a straight port of this game to PC and started active development in mid-October of 2005.
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 colleagues Dr. Rosenberg and Dr. Keller, try to save personell of the facility and reverse the resonance cascade to seal the dimensional rift.
Unlike other games in the series Decay is a cooperative game and its storyline is divided into “chapters”. You must play through the whole game with both Gina and Colette, you can switch between them when in SP mode, though AI controlled bot won’t follow you and will only shoot the enemies. However various puzzles and combat situations throughout the game require the co-operation of the two characters.
Also Decay has a ranking system for all of its nine missions, ranging from F (worst) to A (best), based on accuracy, number of enemies killed, and damage taken. If all nine missions are achieved with an A level, a bonus mission, Xen Attacks, can be played as a pair of Vortigaunts.
Decay opens both new and old areas of Black Mesa research facility, such as Gamma labs and Training Facility.

Whilst this mod can be described as single player it requires you to control two characters at once and you must switch between the two.
When setting your key assignments DO NOT assign the G key because this is needed to switch characters and there is no way (That I can see) to change this. I had to reinstall the mod after I found this out.
