A note from last week on penguin-centric Phoronix reveals that Valve has made a low-key release of a Linux edition of the original Half-Life, saying this is still considered a beta, which may explain why the Steam page for the classic first-person shooter still only shows Windows support. Cult of Mac adds that the game has likewise received an OS X edition, which is also not listed, but available in the library of those who own the game. Thanks Polygon.
