It's the first time i actually have pity for a zombie.
If you mute music and watch him during a research you'll know what i mean.
You can see all his facial expressions, he looks kinda.. sad.
Plus you can molest it, or even kill it and get a new one.
Maybe there are more games like this, but than i haven't come across them.
So this is a quite uniqe experience for me. Thanks for that
