VD-dev while not really well known do have a history with pushing the limits of handheld hardware development. The above screen was taken directly from the game running on the 3DS. While it looks like something along the lines of Resident Evil: Revelations, a third person shooter in a detailed enviornment, IronFall has been confirmed by the developer to be running at 60fps, which is something RE: Revelations could only dream about much less even getting to 30fps.
Seeing the game running on the 3DS with such detail makes one think about how much untapped potential the 3DS really has? The system has been out for a solid two and a half years and it seems to be just coming into it's own.
VD-dev has confirmed that IronFall is a 3DS exclusive since making the game look the way it does most likely only comes at the cost of having the game developed right to the microchips of the 3DS and not ported from another engine made to run on another platform.
Look for the first video of this game in action sometime in the next 2 weeks!
