Onryō: First Seal

From BoardGameGeek:

The ritual has begun. Coordinate or fall. Onryō: First Seal is a fast-paced, standalone cooperative tactical game steeped in Japanese folklore. Serving as the prequel to Onryō: Seeking Solace, the story unfolds centuries before the ancient chains are shattered. From the dark fissures of the underworld, the Onryō has awakened-a terrifying spirit born from ultimate betrayal and driven by absolute vengeance. Sweeping across the land, her wrath stirs ancient Yōkai spirits. If she recruits eight spirits, she will become an unstoppable force of destruction. As elite ninjas from three distinct clans, players represent the land's final line of defense. Stepping into the shadows armed only with stealth and pure cooperation, you must enter the corrupted grid, coordinate team movements, and trap the vengeful spirit before time runs out. For an even greater challenge, enter Tatari Mode, where every recruited monster makes the Onryō stronger and triggers unpredictable disruptions to your plans. -description from the publisher
