How to unlock the Merciful achievement in Naughty Bear - Definitive Guide
Very obviously you do not want to kill the bears so you may want to move your finger off the RT button all together in case of a slip up.
The trick to this is to leave things undestroyed. Whenever a bear runs to an item say either to escape or call the cops when you run up to them you will be given the option to give an Ultra Scare by pressing LT. Little things you can do too like sabotage machines and other objects to attract them to them to repair them, in which case you have the same Ultra Scare Option.
Make sure that you leave thing undestroyed smart. I would recomend destroying the objects of escape or rescue at one end of the level and focus all your energy on one area instead of having to tear from one end to another when bears are trying to escape.
Most bears will take 2 Ultra Scares and then you can leave them to run around after you see the bubble over thier heads, make sure you don't give them a scare after that though because they will kill themselves and you will have to restart.
This will take a bit of patience and constant back and forths to the forest. Try to avoid mines as they can kill bears and cost you the achievement.
Very simple, drive all the bears mad, fastest is by sabotaging objects then doing an L2 super scare when they are repairing it. Mix in a lot of regular boo's as well. When a bear goes insane leave him be and work on the rest. After the first area don't kill the bears just move on and do the same in the next area. This is best done in 1-3 where the bears are not so strong.
For this achievement you need to push every bear to insanity, but do not kill them. Use traps, hit them a couple of times, boo them, but not too much. Just stop scaring them, and move on to the next bear when you see the bubbles above there head. Once you have every bear insane simply move on to the next part of the episode, the achievement will unlock after you enter Naughty's hut.
