Isn't that...sort of cheating? I mean you abuse the camera to look around a wall that your character shouldn't be able to see in his current position...it feels really cheap and what's wrong with just leaning?
Also I haven't played R6 or the DXHR leak, but judging from video previews the constant switching between 3rd person and 1st person looks really disorientating and quite unnecessary...I'm guessing it's not that bad when you actually play it?
Heh in a game like R6, yeah it's cheating. But Vegas was a pretty pathetic Rainbow Six game, pretty fun FPS though. In DX3, it's not that big a deal, although it would be cool to deny people that superb awareness. Beware the fans though, heh.
