In October 2005, work was begun by a group of Ukrainian developers to
port Decay over to
Windows, as a
modification for both the old
World Opponent Network and current
Steam versions of
Half-Life. The port relied on the discovery of a method that allowed
Decay's PS2 game files to be deciphered, thereby allowing the files to be ported to Windows.
[7] The port went into the
beta development stage in December 2007 and was released publicly on September 23, 2008.
[20] The port was received well by the journalists in the industry;
GameSpy site
Planet Half-Life noted that it was a shame that an official PC version of
Decay never emerged,
[21] while British journalist Alec Meer stated that it was "fantastic to have this short but sweet lost
Half-Life episode on PC at last, and it even has something the PS2 version didn't—online play"
