Scale a mysterious tower by skilfully using the controller: that's the challenge set by 'Jusant', a new climbing video game and the latest offering from French studio Don't Nod. Climbing is part of the classic video game hero's kit, but it's often automated, reduced to running straight into a wall while holding down a button. In 'Jusant', you have to prepare each route like a real climber, managing a rope and pitons or even gauging the strength of the wind. IMAGES AND SOUNDBITES
