Naughty Bear is one of the most hilariously disturbing games I've ever played.
There are many ways you can play with other bears heads, making them get nervous, eventually going insane. Then you decide to do with them. You can burn their faces on lit bbq's, blow them up with land mines or quite simple,y make them commit suicide.
It's really kind of fun (albeit in a sick way) to manipulate these bears fears and brutally dispose of them.
Much of the game can be finished by running around, clubbing teddy bears and finishing them off. Some can't though, those ones require much stealth and cunning to pass.
You face increasingly tougher enemies as the game goes on, such as zombears, robo-bears and my personal favourite, alien-bears. They have various strengths and weaknesses, with some posing more of a challenge than others.
After the main story, you get to play out the same scenario with four different challenges including time trial and invisible challenges. The most enjoyable one for me is the killer mode, where the point is to just kill those treacherous teddy's.
You can unlock costumes that give you different upgrades, like master naughty and zombear naughty.
There are a few mechanical issues with the game. For instance, the camera control can get wonky and sometimes context sensitive controls seem delayed. The game is also repetitive.
Aside from it's faults, and it does have them, it is a pretty fun game. It could've been better, but for what it is it's a decent bargian-binner.
