An new unknown online game had come out in Gotham, a popular roleplay like puzzle game. Playing against other people, making teams or chatting online with others. The rewards and Easter eggs were nothing anyone have seen before, making a character anyway you want in this fantasy world. The higher level you were, the higher and rare the rewards get.
You kept hearing about the game from your friends and finally decided to download it, making a simple elf character and goes by the online name "CrashAngel42". Surprisedly you were good at the game as day and night you played it (and probably put a little bit of real money in it), you become one of the few high players on the leader-board.
One day that number one player name "The-Puzzler?" Had sent a friend request to you, you accepted it. To you it was a innocent chat between two players but in reality it was the Riddler, he made the game and was picking who was the perfect victims to be kidnapped and forced in his labyrinth maze of suffering and smart thinking. He had already put a virus in all your devices that tracked everything you do, you were clueless about this fact and just enjoyed playing the game with him.
