Killer7 is a really different game that has moments that just confuse me. The game is a mix between a on rail shooter, mystery, and puzzle game and while it sounds horrible, it honestly works together pretty well. All of the characters have a good amount of mystery to them and are a bit off-putting. You never fully know what is happening in the game and this works well to carry the story throughout the game. Each level has a different plot, and while there is a main overarching plot, it feels like the story hops around a bit. The boss fights are probably the best part of the game with each having a different gimmick and are very interesting encounters. Killer7's style does make it one of a kind, but with some rough edges, I'd say only go in if you want something different.
