Valve has announced a major release for their fresh Mac OS Steam client – none other than Half-Life 2. Mac OS X gamers can now find out what they have missed in one of the most highly regarded FPS titles of all time.

To celebrate the momentous occasion, Valve has released a pretty impressive CGI advertorial homage to Apple’s “1984” television commercial which introduced the Macintosh computer. 

The original Macintosh “1984” commercial aired during the 1983 American Football Super Bowl, creating quite a stir in the media for breaking the mould on prime time advertising. The commercial was directed by Ridley Scott, and used the theme of George Orwell’s novel Nineteen Eighty-Four to ‘hammer’ home how revolutionary Apple considered their Macintosh to be.

Having viewed both videos, and considering the storyline of the game, one can see how Valve has cleverly brought all of this full circle for the Mac OS X release of Half-Life 2. There is no word on any special launch price for the Mac OS X version as of yet, but keep your eyes peeled. Half-Life 2 is currently listed on Steam for US$19.99 (±R156).
