There are only so many Friday the 13th movies, meaning that there's only so many maps and so many Jason's that they can add into the game. Eventually, Gun will have to start to introduce custom maps and custom Jasons, like they did with eight bit Jason.
After taking a look at the new Friday The 13th phone app [Friday The 13th: Puzzle Killer] I came across this.
I think it would be fucking awesome for a 'Crystal Lake Ski Resort' map. Taking Jason and the counselors to a completely different setting with snow everywhere.
Along with the new map could be a new Jason. 'Frozen Jason', donning a blood-stained winter parka, wielding an ice pick (or a ski pole) and a frozen face underneath the mask.
This also opens up new possibilities to new kills like a Hot Tub kill, a Ski Lift kill or something like a new winter-themed counselor clothing pack.
