X-COM: Enemy Unknown

Extra-terrestrial murderous force

Alien soldiers are here

Bio-computer energy source

Nations united in fear

Ethereal psychics with laser guns

So send in the grunts who'll fight not run

They'll enslave the world

So let's save the world

X-Com: Enemy Unknown

UFO crash sites litter the globe

Thousands of homes are destroyed

Mutant creation, alien probe

Masters of combat deployed

Cattle mutilations were just the start

Now civilian deaths are off the chart

Military missions have become routine

Sending out the troops to another bloody scene

X-Com: Enemy Unknown

Fight for territory

Our home

"Two possibilities exist

Either we are alone in the universe or we are not

Both are equally terrifying"

Planetary defence was the ultimate aim

But to destroy them at source has become the game

They came from Mars

Beyond the stars

X-Com: Enemy Unknown

Far from territory

Our home
