Valve parody Apple's 1984 ad for Half-Life 2 Mac teaser

Taking their original Apple print ad parodies to the next logical level, Half Life and Portal creators Valve have just released (as in, minutes ago — hold steady if the YouTube upload quality's still not the greatest) this teaser trailer for Half Life 2's release by giving Apple's classic 1984 ad the full City 17 treatment.

The OSX version of the game will be coming tomorrow to their new Mac version of Steam.
