There are many different zones in Bad Christmas starting at the North Pole and working your way down to the South Pole.
Starting out in the toy shop you then work your way through Santa's Village, now filled with the undead. After that you go through the mountains and an evil forest, fighting more twisted Christmas creatures.
Then once you make it to the city drunk mall Santas that work for Krampus start coming after you.
Then you work your way through a long and barren desert were not so happy Gingerbread Men try and stop you.
On the islands of the South Pole pengins that are jelous of not being elves come at you.
After finally reaching the south pole you face Yetis.
Than finally reach Krampus's layer where you save Santa!!!
