Wow,

Really fleshed out and well made, 
count me as interested.

Edit: Also, if this is a zombie rp, what would be the degree of the strength of them?

I will include the behaviour of the infected and overall sturdiness soon. But it's something like this:

Newer zombies may rarely use primitive tools, such as using a heavy brick to smash a window, but none have any high-level abilities to use items in their environment. Zombies are not shown to be able to "communicate" with others by any means, though zombies will frequently copy the actions they witness other zombies perform, such as bashing on a door or moving in a group. 

A zombie's body will decay over time, a freshly reanimated corpse is much more sturdy and capable of taking multiple blows to the head then a zombie that is several years old. A zombie also uses the full potential of the Human muscles, capable of ripping open a Human's chest and at short range they will overpower the average individual. Their primary instinct would be to bite but they can also throw a punch first.

Though zombies retain a physical resemblance to the living, cognitive similarities are almost non-existent beyond low-level functions, though there are examples of behavior that suggest zombies may retain small fragments of memory of their past lives. Zombies have enough intelligence to walk upright, to use their bodies to break objects, and to climb around or over somewhat small obstacles such as chain-link fences. Zombies can ascend and descend staircases, as well as climb ladders, but they do so very clumsily and slowly. They cannot operate doors or gates, and prefer bashing through obstacles rather than traversing them.

Mostly, zombies are void of any emotional expression and thought. When stimulated, whether by noise, sight of prey, or simply encountering a problem they cannot solve, such as being unable to open a locked door, they quickly descend into a state of murderous aggression. If they spot prey when stimulated, they can pursue them ceaselessly, showing ravenous hunger. They are not hunters, however, and take no concern in alerting their victims or trying to hunt them with intelligence, always seeming to roar, grunt, and growl whenever they are stimulated. Zombies seem to be drawn to noise, presumably because they attribute the source of the noise to be caused by potential victims. Zombies also tend to form groups and stick together, and mimic the actions of other zombies, giving them a mob mentality
