Monolith

Imminent decay of life
Ruthless, dead monolith
Human race will be devoured
Cannibals

Ghoulish - undead vanguard, silent killers, striking quickly
Blood lust - for the living, eat their flesh, drink their blood
Callous - in their method, murderers, murderers
Horrific infiltration, monolith of undead
Slay the living
Is the only object for this bestial rotting horde
Slaughtering the helpless, slaughter all that lives
Driven by an evil force, to feed on humankind
Exterminate resistance, exterminate them all
Cunning and yet mindless stealthfully they kill
Army of decay plodding toward the breathing ones
Countless decomposing corpses walk upon the earth
Outnumbering the living, soon they'll be extinct

Zombies, seek life
Mindless killing all in sight, addicted to entrails
They crave warm flesh
Hunting, dead seek
Ruthless feeding on the weak, savagery prevails
Tear them to shreds
Fighting, undead
Flesh wounds bleeding black not red, invincible undead force
There is no hope
Zombies, devour
Quicken mankind's final hour, fate will run it's course
There is no hope

Walking dead surround, search for living flesh
Ambush on the town, takes a shocking toll
Screams of living fade as the dead destroy their lives
They die
Hollowed bodies heap, empty carcasses
Innards are devoured by the mob of ghouls
