The latest Assassin’s Creed game, Assassin’s Creed: Syndicate, augments the usual killing-evil-people gear players have come to know and love with a Batman-like rope launcher for scaling buildings. But could you really build one, and would it work?

That’s the question that apparently inspired YouTuber and inventor Colin Furze, who teamed with developer Ubisoft to make real-life, game-accurate versions of the gauntlets players wear as Assassins. And it turns out, with a few modifications for safety’s sake, yes: you can build gloves that shoot hooks and allow you to scale walls. Slowly, granted, but hey, begging Assassins can’t be choosy Assassins.

Furze also created a working version of the Assassin’s Creed series mainstay weapon, the hidden blade—a knife that pops out of an Assassin’s sleeve for quick kills in the crowd. Furze’s version looks pretty deadly, too, as he uses it to slice up inanimate objects and definitely not an ancient Illuminati-like group of people bent on dominating the world. Click through at the end of the video for some pretty interesting looks at how he made the weapons, while you’re at it.
