No More Heroes has a social game spinoff in Japan called No More Heroes: World Ranker. You start the game by creating an assassin by picking your gender, clothes, and weapons. Then you can complete missions, level up, and get better gear to kill other players. The goal of No More Heroes: World Ranker is to be the best assassin.
Goichi Suda, CEO of Grasshopper Manufacture, is the producer of No More Heroes: World Ranker. The game came out for Android a few weeks ago and now it’s on iOS too.
Like other social games, No More Heroes: World Ranker is free to play, but some virtual items cost real world money. You can grab it here:
