Polterguys: Possession Party from Madorium Ltd is a party game that's highly competitive. As a bunch of ghosts, you and friends are trying to get away from a monster, so you need to sabotage everyone else to survive. Note: key provided by the developer.
Since you're a ghost, you need to fly around and posses various items to gain just a little protection. While your friends are doing the same, it's a game of last ghost standing. Speed is not the key, tactics are, you're trying not to get caught while ensuring everyone else does. You get various powerups to help with that, and each level has a different mechanic to help you try and trap others or hide from the monster.

Nice to see a party game that isn't local multiplayer only as well. You can do both local and online play, so it has the best of both worlds for friends near and far to compete. A nice casual competitive party game that's a good time with a few friends, a spin on hide and seek.
