PCG:On screen, Lara Croft is inching her way up a rock face. She’s wedged in a narrow vertical gap, chimneying her way up. It’s complicated, gruelling work. She grunts as she works her way past outcrops, exerting herself totally with the effort of remaining suspended some 40 feet above the jagged ground below. She slips, losing her footing for a second, before she jams her boot against the wall, steadies herself, and heaves a lungful of air. She climbs on.
