I don't know if this is a bug or not, but it was interesting and could be useful.
If the last enemy is taken out with berserker fire, does it count them in the score? I have a map that had 4 enemies, ninjas. 1 was definitely killed, 2 were stunned, and the last was hit by a berserking hand, I don't know if she was killed or stunned, and 1 lokk'narr was killed. ended up with 1 kill, 2 captures, and 2 looted corpses. I don't know if you ever loot civilians.
Actually would be useful to know in general if berserk kills count to the score, either positive or negative.
