This is a fantastic board game, and a ton of fun to play. You and other intrepid explorers build a haunted house, avoid literal pitfalls into the dreaded basement, and eventually, start the haunt. Then the game moves seamlessly into betrayal mode - one player (or a giant bird, or whatever) becomes the enemy, and the rest of the players must work together (or stab each other in the back on their way out the front door) to survive.
There are a ton of different haunts, and even with dozens of playthroughs I haven't been in the same situation twice. It's easy to pick up, and will keep everyone involved til the end. Dim the lights, put on some spooky music, and have fun!
