Ambitious, unofficial Half-Life expansion wraps up a 24-year-old cliffhanger

You think of Half-Life, and you immediately think Valve. It's a series synonymous with Steam and PC gaming as a whole, but it has ventured onto other platforms, too. No, I'm not talking about Alyx (which is still a Steam-only game, despite the fact that you can play it on non-Valve headsets), this is Half-Life: Decay. This DLC for the original game was designed by Randy Pitchford and developed by Gearbox Software for the PlayStation 2 back in 2001. If you ever wanted to learn the fate of Drs. Colette Green and Gina Cross, you'll finally be able to, thanks to a new set of mods.
