Naughty and Nice: Available after you complete the DLC campaign.
Easy -> Rosen Oaks (Far right side and middle of the map)
Medium -> Brickston (Far left side and middle of the map)
Hard -> Yearwood (Far left side bottom of the map. Close to medium one)
If you are having trouble locating these, please go to your map and use the D-pad to put only activities on. When these activities appear they will be question marks and say unknown GPS.
To do: You will be delivering presents, similar to the last mission in the DLC. You will gain points and multipliers by shooting naughty houses with coal (Right Trigger or Normal fire) and only mulitpliers for Nice houses with presents (Left Trigger or Alternate fire).
You will gain points for shooting the alien sleighs as well.
You will gain points and must medal within the time limit for the achievement to pop.
This will count towards Vehicular Mayhem medals, so if you are missing gold on those challenges, getting gold on these will count towards completing that challenge.
