One of the centerpieces of Assassin’s Creed Syndicate is Jacob Frye’s wrist-mounted rope launcher — he can scale buildings like a Victorian-era Batman. But would such a thing be possible in real life? If you ask Colin Furze, the answer is yes… sort of. As part of a promo for Ubisoft, the inventor built a real rope launcher gauntlet that uses a carbon dioxide canister to propel the line, and a motorized winch to hoist you up. You wouldn’t want to use it for any daring escapes: it’s bulky, slow, and needs a harness to support your weight. However, the very fact that it works at all is impressive. If you ever need to fight Templars (or just want to climb walls with ease), you’ll want to ask Furze for some pointers.
