Even after watching this movie, the game still doesn't make much sense. But man, does it look amazing.
Capcom of Japan has updated their Killer7 website with a game trailer. This particular trailer just happens to be the one that was shown at TGS last month.
The trailer shows off how bloody and cel-shaded the game will turn out to be. There is a lot of shooting, a lot of killing, and a lot of blood being spilled, all in that shaded fashion. You can see all seven of the main character's "personalities" in motion as well.
The movies come in two sizes, the 13 MB low-res version and the giant 30 MB
hi-res version. Even though the download size is hefty, you should give them a look if you're even the least bit interested in this game.
