Hyakki Castle, as we saw in September, is a grid-based dungeon crawler—think Eye of the Beholder if you're old, Legend of Grimrock if you're not—that trades conventional D&D-style fantasy trappings for the 18th-century Edo period of Japan. Today publisher Happinet revealed the launch date of November 15, and also a new trailer that showcases some of the monsters and puzzles you'll encounter in the castle's haunted halls. 

One of Hyakki Castle's most interesting features is the ability to split your party into two separate groups. As the trailer demonstrates, this enables you to flank enemies, attacking them from two directions simultaneously, and also opens the door to some potentially interesting opportunities for two-part puzzles.
