Warm Snow – How to unlock the bond between the mother and the missing brother

There are two items that are needed to unlock the achievement. The first of which is the rotten bun, which is a random drop. I got it just before the nameless swordsman fight, but I think you can get it in any scene in that chapter. The second is the Message from the Mother, which only drops in a secret area in a specific scene in chapter 1 before the first boss/mini-boss fight.

 

It looks like this when you enter. I got this cutscene by taking the first left after entering the settlement, but the levels in this game are semi-random, so there's no point in memorizing specific path options.

Once you've reached the scene, head up and to the left.

 

If you are in the correct scene, you will see a zombie boy and a boy by a tree behind a building.

You can't get to them from this side, so head up, then left and back down.

My character is looking to the right in this image, but the correct way to do it is to the left.

Instead of heading left to the end of the level, head down and to the right. There is a hidden path.

Neither child is hostile, but the zombie must be killed to receive the mother's message.

Ignore the pink monster, on my difficulty level each enemy I kill has a high chance of spawning one. If you play on a lower difficulty, the pink monster may not appear.
