This is Devil Summoner: Soul Hackers, an Atlus-developed role-playing game for 3DS that's part of the Shin Megami Tensei series. It's a first-person dungeon crawler set, like most SMT games, in a demon-filled version of Japan.
I think this is the first trailer that Atlus USA has released for Soul Hackers, which was originally released for Sega Saturn and then PS1 in Japan. This is the first U.S. release for the cyberpunky RPG. It'll be out this spring.
