If I ever found myself double-booked in a hotel, I’d probably try to make a bed out of my suitcase and find a broom closet to sleep in so as not to make a fuss. Not so the player characters in multiplayer brawler Check-In, Knock-Out. Rather recklessly, in an attempt to claim the room they start lobbing the furniture at one another and end up tearing the whole place apart. Originally created as a school assignment, Check-In, Knock-out is being touched up for a full release. It looks like Smash Brothers with destructible environments.
