[C'tan]
From the dark of space [bad word] now
littering the soil with deadly spores

Planetary defenses fail to
stop this invasion of orks

Humid wet plains of this land 
breeding ground for whats [bad word] 
Genetic memory of the green kind
to start building and amassing arms

[C'tan]
Dark days fall upon this place;
ecosystems in disarray

The killing begins again
Nothing ever changes, it's all the same

[Humans]
They kill our mothers
and decapitate our sons

What more to expect from savage beasts
with savage tongues?

They speak of domination,
yet they do not know

Science and reason [bad word] to this planet
and take control

[C'tan]
Mobs turn into warbands
and quickly into tribes
Ork on ork violence [bad word] and stops

Weapons made from schematics
tucked away in their heads.
warboss emerges to lead them to death...

[Ork]
Die...
Faunic scum!

If the manifested beings do not kill you
you will succumb to death from inhalation.

Lungs, they decay. 
As they grasp for their last oxygen intake.
