As for what it looks like: it's in full 3D, with slightly more success than you'd expect on the DS. The game keeps a mostly top-down perspective, like another early 3D stealth game we know, but seems to close in on combat scenes. The whole thing actually looks fairly sophisticated and nice, for a game we continue to be very suspicious about.
We imagine that it plays similarly to a more acrobatic Metal Gear Solid, as well, with the bottom screen acting as radar. You can also choose from the dozen or so available weapons via the touchscreen.
