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.

You can watch a polished video detailing the Nosulus Rift's creation above (complete with smooth panning shots and talking head designers), but for a more detailed experience, check out the hands-on from Gamespot below. If the presenters' reactions are anything to go by, the Nosulus Rift is genuinely disgusting to use. South Park: The Fractured But Whole is being released December 6th for Xbox One, PS4, and PC. Gamers will have to supply their own smells.
