Killer 7 is "cool." And with its unusual premise, stylized violence and ghosts in gimp suits, it can't go more than 15 seconds without reminding anyone within earshot just how cool it is. Sort of like Quentin Tarantino.
In other words, its pretentious and not much fun.
Yes, Killer 7 is from Goichi Suda, the same man who gave the world No More Heroes, one of the Reasons To Own A Wii. The difference between the two games is that No More Heroes lets you play it while Killer 7 mostly makes you watch.
Most of the game is spent holding down the A button and watching your killer run around from highly cinematic camera angles, waiting to find a ghost to talk to or to hear the tell-tale cackle of one of the Heaven Smile ghouls, which means its time to shoot something. When that happens, Killer 7 becomes a first-person shooter, albeit a first-person shooter in which your character is rooted to the spot.
The rest of the time, Killer 7 is an animated choose your own adventure book. Want to use the stars? Go to page 43. Talk to the guy holding the luchador mask? Page 38.
