In the upcoming South Park game, South Park: The Fractured But Whole (say it aloud... yep), one of the key mechanics is farting. You can fart to fight, fart to move around, and fart just for fun. And so, as part of their press tour for the game, publishers Ubisoft have built the Nosulus Rift — a mask-shaped peripheral that delivers fart smells straight into your nose as you play the game. To be clear, this is an actual, functioning device, although Ubisoft says it's only available during conventions like Gamescom.
