Launch maps are the ones each game shipped with, the same list the minimap quiz uses. Every map adds seasonal and post-launch maps.
One point for each thing you guess. If a map appeared in more than one Call of Duty, any of those titles counts. Typed map names that are close or only partly right get half credit.
Minimap images and map lists come from the Call of Duty Fandom wiki (CC BY-SA). Base-release multiplayer maps only. The wiki has no minimaps for Call of Duty 2 or Call of Duty 3. Loading screens come from the map pictures on the wiki's Maps page, DLC and seasonal maps included.
