Naughty Bear is hell-bent on revenge. The other bears have been nasty to him for too long and he's had enough. Naughty has now set about on a mischievous mission to make them pay for what they have done.
In each level, you'll find all sorts of weapons including axes, clubs and knives to exact some creative revenge on your fluffy foes. Once you've selected your tool of destruction, you can go and find some bears and be very naughty. Along with weapons to terrorise your opponents, there are also a few bear traps lying around for you to set for unsuspecting passers-by. Once stuck in a trap, they're much easier to attack, or just send insane.
Challenges vary between the different levels from wiping out all the bears in sight as quick as you can, to sending them all insane. The more bears you dispose of, the more naughty points you will receive and levels you will unlock. Naughty points can also be earned by using lots of deadly weapons, destroying the other bears' possessions and scaring the living daylights out of them.
It is important to remember that naughty points are measured by naughtiness, so it is in your best interests to be as inventive and devious as possible when causing havoc.
