You are Leifren Von Green, a powerful bounty hunter with a magical green hat granting unlimited ammunition for any weapon, with the condition that you solve some math problems for it, of course. You'll be fighting off hordes of zombies, skeletons, and other generic monsters as a one man army and your next target is an arrogant, power-hungry necromancer that desires nothing less than the death of all things green.
