Missable achievement found in Wyatt's chapter. Please see "Abandoner" for specific details on where in the story it comes up, and what to do. Below is a quick synopsis of what you need to do:
After you hit the person in the car, and following some dialog you will have the opportunity to play Eddie in a game of rock/paper/scissors to see who will get out of the car and go see who/what that was. Your four buttons will represent the three choices while the forth will represent abstaining which will end the game. It's completely luck based so don't fret if you are unable to best Eddie right away, or on the first try. Note that if you lost a game quickly go to the main menu and exit out to avoid having to replay the entire chapter. Once you beat him in the best 2 out of 3 you will unlock the achievement.
