This was previously glitched and unobtainable but it has been patched and unlocks now.
You just need to escape with an item another player had before you load in to the match. So pay attention to what character has what while at the campfire lobby.
I don't know if you're required to bring in an item too.
You are allowed to place the item down. I grabbed a med-kit out of a chest to heal myself and then picked up the other players item again and still got the achievement.
Three ways exist for you to get another players item.
First way is to pick up a dropped item after a player has been killed by the killer. if they're killed via sacrifice on a hook, just go to that hook and it should be on the floor. If the killer killed the player via Memento Mori or the player bled out, you'll have to search for the spot where they died.
Second means of getting another players item is if they leave the one they brought in at chest. Maybe they brought in an item for whatever reason and in a chest they find a better one. Obviously most people will take the better item.
Third way will require you to bring in an item of your own. Make your top priority to find whatever other players had an item in the lobby and then drop your item on the ground next to them with the
button, if they pick up your item you then can pick up theirs. So bring something worth while that they'll be willing to swap for like a toolbox or med-kit and maybe have it be at least uncommon (yellow colored) rarity in the off chance they brought in a common (brown) item.
I'll test this achievement with other profiles but please let me know if you find any of this to be inaccurate.
