Deus Ex: Human Revolution, the latter is a decidedly PC-only affair.
But like the original Deus Ex, which was ported to Mac OS shortly after its release, Human Revolution will enjoy a Mac OS release courtesy of the good people at Feral Interactive sometime this "winter 2011/12." Specifics on pricing, date, and system requirements will be announced "later this year."
Eidos Montreal general manager Stephane D'Astous says, "We are delighted to partner with Feral, a leading expert in development for the Mac platform, to bring the acclaimed Deus Ex: Human Revolution to Mac players." With two million units already shipped, a Mac release should help Eidos Montreal's surprise hit find an even larger audience.
