428〜封鎖された渋谷で〜 is a Visual Novel by Chunsoft and published by SEGA.
From what I can tell, Visual Novels that aren't Phoenix Wright aren't too popular around here, but this one is different.
428 is entirely in live action(with the exception of the extra scenario), and has multiple main characters, each of them with their own perspective of the story. The whole thing is kinda hard to explain, but think of it as something like 24 or the like, but more interactive, and different endings.
I normally wouldn't be so interested in the game, however, Famitsu, one of the most respected and largest Gaming Magazines in Japan, gave this game a perfect 40/40. That's right, Famitsu apparently thinks this game is as good as OoT, Wind Waker, MGS4, and Brawl, and is BETTER than GTA4, Okami, and Phantom Hourglass.
This must be one KICKASS visual novel then.
Chances of it coming to the west are shaky. VNs have seen a wave of popularity with Phoenix Wright, Hotel Dusk, and Trace Memory, but the whole live action thing might hurt it.
