Neither Seen Nor Heard Achievement
I actually didn’t realize there was any kind of stealth killing in this game, mainly because I tried to sneak up on a Lewolan at the beginning and it was noticing my presence without any kind of prompt for me to do something.
It makes me think stealth killing is only available to human enemies.
I’m not sure why I tried to sneak up to someone. I think I figured I could pickpocket a key off of an enemy that I needed to free a fellow native in The Escape.
Which might be the best quest in order to go for this achievement, honestly.
To obtain the achievement, sneak up behind an enemy without them noticing you. Once close enough, you’ll get the prompt to knock them out. After doing so, I guess they’re technically dead and you can loot them.
