We are no strangers to PiKISS, Jose Cerrejon’s fantastic tool to simply add extra features to Raspberry Pi OS and Twister OS. PiKISS comes with a special section of installable retro games for the Raspberry Pi and in there Jose has recently added a fully playable version of Half Life configured for the Raspberry Pi 4 (via leepspvideo and ETA PRIME).
Installation of PiKISS is via a single line of code in the terminal which will download the installer and then run via the terminal. Once installed PiKISS is found in the System Tools menu. In PiKISS look for the Games menu and then select Half Life to download and install. You do need to own a copy of Half Life for this to work, either a digital copy from Steam or a physical copy.
Once installed the game is all set to be played, so have your crowbar handy to fend off a headcrab or two!
