As I understand it, this game is based on jobs, right?
Then, what about a Ghost hunter minigame?
Origin:
Your friend started to work for a church and as he needed a partner he takes you that work. Then he is abducted by some random devil tentacles that came out from a house
Game-style:
It's a 2 dimentional game (you see it from the side). In here you have to go across rooms in an "infinite" hunted house/mansion, you has to fight some weird infernal things and purge them, you can dodge the attacks by jumping or crouching and you have some items (Holy Water->Bible->Crucifix...Silver knife->Silver Arrow->Silver Bullet...Garlik-Stake->Stake crossobw...Etc.) A basic power depending on the character selected (Intern-Cultist-Priest...)
It would be cool for a 2.0.0 version
Thanks you for reading all this
