It might be a good idea to sharpen your Extreme Exorcism skills before the game arrives later this month. The paranormal platformer will be available on September 23 in the Nintendo eShop for Wii U, and it will cost $12.99. In Extreme Exorcism, players are tasked with exterminating all ghosts in a haunted house. There’s a twist to it, too, with each new round ghosts will mimic your prior actions to the point where you’re essentially competing against yourself. The game was featured in the Nindies@Home program in June.
