Warnings

The macOS (OS X) version of this game does not work on macOS Catalina (version 10.15) or later due to the removal of support for 32-bit-only apps.

Half-Life 2 is a singleplayer first-person FPS game in the Half-Life series.

The retail release was published by Sierra Entertainment up until the publisher lost all publishing rights to Valve's titles in 2005. Valve subsequently partnered with Electronic Arts to distribute later retail versions of the game and future titles. The macOS X version was released in 2010 and the Linux version later in 2013, both coinciding with the launch of Steam on their respective platforms.

Like most of Valve's library, the game still receives bug fixes and general maintenance updates. It also enjoys a large community base, and various mods are released regularly.

    "Fix missing music/sound effects in Source Engine games (Valve games, etc.) on Fedora
    Unfortunately, on Fedora, some Valve games have a bit of an issue regarding completely skipping playing certain audio files. None of this causes any crashing, but can lead to a worse gaming experience, confusion, and the appearance of buggyness- and generally isn’t great. To work around this, please refer to the following steps, and all the games’ audio will then work perfectly.
    You need to open your Terminal emulator, either from the usual application menu place, or by using the keyboard shortcut Ctrl+Alt+T, or sometimes it’s Super+T AND THEN type the following into it, entering your password when it prompts you.
    sudo su
    sudo setsebool -P selinuxuser_execheap 1
    That’s it. Your game will now function as intended, enjoy being able to hear the soundtracks, music, sound effects, etc! Especially ‘Still Alive’, and the banger that Half-Life 2’s soundtrack is, amongst others.
    valve pls fix
