Japanese analog game developer Group SNE makes their popular horror themed tabletop RPG "Ghost Hunter" into a fine co-op tile laying board game.
In this newly introduced rendition of the game, as a team, players explore a mysterious mansion to complete several missions ( long forgotten artifacts, monsters hard to beat, mysteries about the mansion, etc etc... ) which bundled scenarios task them. Players can move their chosen heroes ( each one gets uniquely powered and equipped ) up to two tiles. If there's no tile to move in, you may draw as many tiles as you need from a stock for placement.
Tile by tile, the mansion would gradually reveal itself to players. On their explorations, your heroes sustain mental/physical damages ( your characters might go mad or die if it's too much to bear ), fight off some deadly monsters, and discover powerful artifacts to help your team keep on.
