Never mind that this video is titled "Leaked METAL SLUG AUGMENTED REALITY on WII U !!", as it's obviously fake (and likely not even possible, as the Wii U, as far as I know, doesn't even have a rear-facing camera) -- watch this anyway because it's awesome.

If this is where augmented reality games are headed, with awesome sprites taking cover behind real-world objects, blurred items in the foreground and shadows on the floor to emphasize the depth, and four-player co-op, then count me in on this gimmick.
