Space Invaders

Ships from an alien source are approaching from the sky
Radio contact has been attempted
But cannot be established
Instructions are to prepare for an attack
By an unknown enemy

Space Invaders

Light speed in 3, 2, 1

Ravenous beasts, as far as the eye can see
A plague on a surface
A disgusting swarm in the skies
With a crash of thunder a new demon appears
Unfurling it's rotten wings
It lets out a petrifying scream

Final boss

It's time to fight back
