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
