Some might think Zombies climbing up steps requires a bit too much intelligence considering their mindless walking dead state. However, zombies can indeed navigate staircases in a rudimentary manner. Normally they will stagger about on relatively flat surfaces with the occasional stumbling and even tripping over bumps and obstructions. They mostly ignore steps unless there is movement or a smell coming from the direction of the stairs in question. Certainly, you shouldnt believe running up steps...
