Later in the game it ist much better because of perks. But in the beginning it was horrible. Yes i tried to remember where they fell but often the physics throw them far away from the place they died.
After every fight I spend hours trying to find the corpses in the grass. I usually look for the last 1-2 in vain. This is extremely annoying and frustrating. Is there a trick, because that can't be the point of the thing?
