The story has lots of varied levels with ever more brutal ways to convey his opponent to the afterlife. Moreover, the story is quite long so you really get what bid for his money. Through the witty sayings of the characters, the game is also not boring because there are quite a few scenes in which one can properly laugh.
Even the echo mode in which as many points you need to achieve (different kill combos) in a short time by Skill-Shoots, makes a lot of fun because there really is a huge number of these skill-Shoots. Actually the imagination there are no limits.
In multiplayer I had been to find a group after a short time you can start right away and also this mode is very successful in my eyes but the most fun when you have teammates no problems who know what it is so that you the points needed for next level then gets together.
All in all a very good shooter, which should be in every collection. But then, however, as PEGI or UK version, stay away from the USK.
