The lovely folk over at VR Focus have written up a summary of all the achievements you can unlock in The Assembly. Take a look here!
You can also compare how you rank among other players on our Steam achievements page, along with each achievement's icon. (My personal favourite is Wolfie's Fine Honey...)
What's your favourite achievement? Are you in the 0.1% who've collected all the project dossiers? Tell us about it in the forum!
