Now before you just brush this off as another casual iOS game that you may or may not consider to be a "full game," take a look at the announcement trailer below.
As you can see; although it is an iOS game, it is also a full Deus Ex. It will play a lot like Human Revolution, feature a full story, and it will basically have everything you would expect from Deus Ex. It's just that this time around it is on iOS, and not on a console or on the PC. Although it may actually be a pretty good game, I'm sure not many fans are going to be happy about this.
