While most critics have written that Mario Kart 8, the new Nintendo racing game, is more of the same, there is one key, disturbing difference.

BuzzFeed has collected footage of this strange and violent new Luigi, as well as the nihilistic rap songs that he listens to while perpetrating his chilling hate.
