Half-Life: Source

Half-Life: Source’s Linux and Mac OS X beta became available in September 2013, bringing the Source remake to both platforms while remaining explicitly a test release. Half-Life 1 HD Content Pack support followed, alongside a concentrated pass that restored original-game behavior and repaired several campaign-specific problems.

• Cross-platform beta: Half-Life: Source became available on Linux and Mac OS X as a beta, with players encouraged to report bugs during testing.
• Half-Life 1 HD Content Pack: Support was added through the video options, while world-texture changes were removed from the HD addon so it more closely matched the original Half-Life pack.
• Combat fidelity: Several systems were brought closer to Half-Life 1:
  • Glock: Its magazine was corrected to hold 17 bullets.
  • Alien Grunt: Its armor was made to count during fights.
  • Apache: Its health was matched to Half-Life 1, its guns fired correctly, and a crash during Apache battles was fixed.
  • Nihilanth: Its excessive difficulty was adjusted. The same pass added drowning sound effects, fixed muzzle-flash rendering, and corrected the c1a3 sentry-gun logic.
• Campaign reliability: Unforeseen Consequences and Residue Processing regained their missing HEV suit, while Lambda Core received the correct starting map, changing from c3a2 to c3a2e. Audio and presentation issues across c2a1, c4a1, c4a2, c4a3, and Xen were also corrected.
