Matricide Achievement – Arkham Horror: Mother’s Embrace

Matricide Kill the Dark Young with a Birthling explosion.

How to Unlock  Matricide Achievement

Can only be done in “A Mother’s Embrace” (scenario 9). While fighting the Dark Young it will start to spawn the little monsters that explode upon death.

You have to kill the mutated Professor Tillinghast several times and she gets revived each time and siphons health off of the Dark Young. The last time she does this, the Dark Young will have one health remaining.

Lure one of the little Birthlings towards it and once it’s close enough shoot it to have its explosion kill the Dark Young.
