The Case of Misfortune

To start this achievement, you need to find one of the secret cards and then get the quest “Deck Dismay” and complete it.

The very first card is behind the wooden chest that stands next to Alyx (/way #71 63.01, 50.23). Note that the cart only becomes visible when the Idol of Ohn'ahra is activated.

If for some reason you don't see this cart or have already picked it up, but don't know what to do next, go to Deck Dismay to read the step-by-step instructions on how to get and fulfill this quest.

The instructions will help you fulfill all the conditions to get the achievement.
