Deep Down looks like what happens when Capcom figures "let's put Dark Souls and Assassin's Creed together!". It sounds like "I'll have a Deep Down, potato & gravy and three pieces of original recipe chicken, thanks".
Ah well. We don't really know much about the PS4 game, but the clip shown at Sony's pre-TGS presser in Japan sure is something. That weird cut in the middle isn't an ad for PlayStation Home on the PS4. It's showing the game's true setting, which is New York City, the year 2094.
