In Metroidvania, no one can hear you scream

Just acquired this achievement last night in Shadow Complex:

Make ‘Em Scream (20G): Get 100 soldiers to scream

What’s nice about this achievement is two things: 1) it was not one that I had to consciously be aware of achieving, in that I just shot soldiers and tossed grenades their way, and sometimes they’d scream when being blown to bits and other times they’d just crumple to floor and 2) Shadow Complex does a wonderful job of providing in-game tracking towards its achievements so I knew I was getting close to this one, making each further scream all the more rewarding.
