"When referencing the show, one of the things that stood out to us was how the Walkers reacted to sound; they were suspicious of gunfire," said Gonzalez.
"Seeming to know that only humans were able to wield weapons, the Walkers instinctively moved toward the sounds people made. They are also attracted to other sounds, so someone moving through that world needs to be aware of the amount and type of noise they make at all times.
"We're crafting our Walkers to react the same way. In the game, you'll need to carefully sneak into and out of some dangerous situations and you may meet a few Walkers along the way.
"If you show up with guns blazing, you'll quickly find yourself dealing with a much larger crowd and you could easily become overwhelmed."
Gonzalez also revealed that players will give off a greater scent and attract more Walkers by staying in one place for too long.
"Walkers also have the ability to tell the living from the dead by their sense of smell.
"Humans give off a scent that the Walkers can detect, and the longer we stand still (like when we are looking at a shelf for supplies) the larger the radius of that scent becomes. Stand still for too long and a Walker shambling down the street looking for a meal might just discover you standing inside a store."
