To the undead,apocalypse means... Life after death

These corpses revive.
Let's bring them to life.
There's a new world
  to attack.
Now that their appetites
  are back.

Brains!?
Screw that!
They want the whole thing.
Giving life to undead
children.

Reveling...

In the exposure of hearts,
and inner working parts.
Eatin' up the remains
of life...
without chains.
