Rescue the little girls from the ferocious ursine wildlife. Or to put it another way, "Are you a lulzy enough Anon to save over 9000 helpless lolis from oncoming pedobears? If you do, they bring you moar ammo to gun down moar bears with! Also the game! lolololol i troll u!"
Classy fun for the whole family. But remember rules 1 and 2 and what they don't apply to, kiddies! :)
