Vengeful spirits. They can be a real nuissance. And when that spirit is a vengeful samurai spirit, that just makes things that much tougher. But that's what you'll be trying to eradicate in Hunt the Ravager (conversely, you could be the vengeful samurai, which seems like it could be fun). It's a new hidden-movement board game that's up on Kickstarter now.
From the campaign:
Hunt the Ravager is an asymmetric 2-4 player hidden movement game where players take control of a vengeful samurai spirit ravaging the land and the samurai forces of the Empress attempting to put the vengeful spirit to rest.
The game's about 2/3 of the way to its goal with 8 days left to go.
