Original Article
It would appear the iOS release Deus Ex: The Fall is making its way over to Steam. An alert user over at NeoGAF was able to locate some steam links and banners for the game.
No official word as of yet, but there is really no other reason (that we can think of) for this to appear on Steam than the game heading there.
