Naughty Bear

The key to this achievement is speed! Start the level using a fast costume and throw the page into the fire (saves killing the zombears) and smash the statue, pick up the trap on your way out. As soon as you enter the level run and either place the trap in front of one of the normal bears or slash at him. Then race round to the fire where the other bears are and hit the statue and them until you have enough points when you do run round to the gate. Next area run straight to the cabin nibbles should be at the fridge kill him there and then you should have enough points to exit if you run quick enough no other bears will be killed and the achievement will pop.. Good luck

What no one seems to have mentioned is that this can be ridiculously hard unless you play on the speed run level. Simply take out the targets you need as a ninja bear and the speed of attack and the moving speed of you against the zombie means this can be a very easy achievement. I was not even attempting it when I got it. Be aware that you can get fenced in by the zombears so always leave a path but don't wait for a moment. Chances are your end target is in the cabin from the start. Simply leap through a window, take him down with your sword and run for the exit of the level. You should be there before the zombears have had any chance to kill if you do it quick enough.

Speed is the key. The way that I unlocked this is by getting the necessary points as fast as possible. Then I did not even have to kill the normal bears i just had to keep them safe from the zombears until I left the area. Rinse and repeat for each section.

Happy Hunting :)

For this you have to kill all the non zom-bears, meaning a zom bear cant kill a bear.

For one it doesnt matter if a bear kills a zom bear, you will still get the achievemnt if you do it right, and the achievement doesnt pop up as soon as you have killed all bears. After youve completed and your scores are tallyed up you will get the achievement.

My best advice would be to use someone fast, like Master Naughty and run and find all normal bears and kill them, and then kill the rest and progress to the end.

Good Luck :)

Use Master Miyagi or Danger Bear as they are really fast and have a good strength stat too so it'll make it easier. I recommend the speed run challenge.
