Enemies have invaded your homeland and they are trying to take away from you what is rightfully yours. You're a soldier at the last checkpoint. This is the last frontier that deterrent hordes of bloodthirsty mercenaries and murderers. Do not let your enemy win!
P.S. We would also like to thank the developers of the game about swamp and crocodiles (we can't mention their names or the name of the game because of the Google Play terms) for the inspiration.
