After having kind of blown the secret already through their official website, Square Enix has today confirmed that Final Fantasy XIII will be coming to PC this October via Steam and their own online store.
In fact the entire Final Fantasy XIII trilogy will be coming to desktops eventually, with the original game from 2010 first, followed by 2012's XIII-2 and finally 2014's Lightning Returns.
It's currently available to pre-order through Steam with 10% off with Final Fantasy XIII releasing October 9th. The others are expected to complete the trilogy's migration to PC by next spring, says Square.
