The zombie's strength level is at normal human-levels, but they are considerably slower that average humans, possessing poor agility and coordination. Most zombies have difficulty with simple mechanical objects and obstacles such as doorknobs, latches, stairs, and fences.
When confronted individually, zombies appear rather weak, but the creature's true threat is revealed when they are encountered in huge numbers. These relentless legions of tireless, flesh-eating machines will assault you on every side and corner until you fall and there comes the lunch.
