The Assassin's Creed video game franchise uses historical fiction to tell the story of two dueling secret societies, the Assassins and the Knights Templar. As an action-adventure game, a big part of the experience involves interacting with the environment and acquiring (and using) unique weaponry. Inspired by two of the franchise's most iconic weapons, an inventor named Colin Furze has designed and built his own working rope launcher and hidden blade.

Furze shared footage of himself testing the potentially dangerous devices in the real world, and also posted making-of videos to his YouTube channel. It goes without saying that even the most experienced Assassin's Creed players probably shouldn't try this at home.
