Game summary

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.
First released: Nov 2001

Play Half-Life: Decay on Mac with Parallels (virtualized)

The easiest way to play Half-Life: Decay on a Mac is through Parallels, which allows you to virtualize a Windows machine on Macs. The setup is very easy and it works for Apple Silicon Macs as well as for older Intel-based Macs.

Parallels supports the latest version of DirectX and OpenGL, allowing you to play the latest PC games on any Mac. The latest version of DirectX is up to 20% faster.

Our favorite feature of Parallels Desktop is that when you turn off your virtual machine, all the unused disk space gets returned to your main OS, thus minimizing resource waste (which used to be a problem with virtualization).
