Adam's map is a map that appeared in the episode Cradle to Grave. It is unknown, but assumed that Adam made the map (Out of universe, Jon Graham made the map for the episode).
It was a race track that Adam created using Forge mode. It was made using Forge World, and was a race track that was high above the ground. Adam raced his "friends" on the race track at the beginning of the episode. Later in the episode, Adam, pursued by Arbiter and Master Chief, came back to the server. They followed him there, and he went down the race track, with Chief and Arbiter driving after him while firing rockets. Adam was eventually cornered to a platform at the end of the map. At this moment, his mother came in with the police officer Gordon Jones, to take Adam to juvenile hall. While he was taken away, Arbiter fragged him.
