The fabric of reality is in shreds, and monsters are invading! It's up to you to do what it takes. Bring your greatest weapon and do your best, because you are the... Protector of All!
Devastate all the levels and shoot the alien scum in the head, or in the back. It's your choice. In the end, you will get what you deserve. It is hard. It's not good to be in your skin. But with the loot you find, you'll be able to get bigger and more terrifying weapons that will leave a line of dead enemies in their wake! In the end, there will be more bullets in the air than oxygen for everyone to breathe.
