Possible Half-Life 3 Achievements Leaked
Briefly, there was a screenshot via Steam of Half-Life 3 achievements. But, shortly after going up the screenshot was removed. There are rumors of a rather large announcement to be made at Spike VGA’s regarding Half-Life 3 but until it’s confirmed don’t get your hopes up.
At best this is a ploy to raise awareness of a game still in development, at worst a trick. Until the announcement at the VGA’s no one knows.
