Item of Obsession achievement in Dead by Daylight

You can cheese this if you have friends:
Be in a four man swf, ensure no one else has any perks that increase your odds of being the obsession.
Equip the perk "sole survivor". Optionally, there are others that will help you. (I used left behind, spine chill and lightweight)

Equip offerings amongst your group to ensure the hatch spawns in the killer shack, and a map offering that has a shack.

Once you're in the game, get to the shack, get your friends to all DC (pause - leave game) and the hatch will spawn right next to you. Might take some rng as the killer may spawn nearby, and some killers may affect it, but should only take a few tries.
