Mad genius Colin Furze did it. He made one of the coolest video game weapons—that would be the hidden blade and rope launcher in Assassin’s Creed—a reality. It works just as advertised! You can shoot out the grappling hook and then retract the rope to lift yourself up and over walls and buildings (though because this is real life, you need to loop in a harness of sorts). And the hidden blade just pops out and in with the flick of the wrist and is ready for you to slice the hell out of things.
Watch the video below to see Furze play around with it and to become instantly jealous.
