soldier at war, anna and the apocalypse

The streets are chaos and the outlook is dire
Time for a hero to step into the fire
The world's a jungle and we're close to extinction
This is my moment, and I'll fight with distinction
We must stay focused, keep your concentration
Look to have fun and use your imagination
No time for weakness when the undead are waitin'
So let's get out there and start decapitatin'
When it comes to killin' zombies, I'm the top of my class
While you've been hidin', I've been kickin' some ass
I know the best form of defense is attack
I know what I'm fightin' for, I'm a soldier at war
