I am thinking Frankenbrutein may disappear after 31 Oct. But hoping the game would keep him. May be it will become SantaClausBrute in the Chrismas event? That would be great.
I'm sure he will be leaving once the update patch goes through. I can see them adding a new visitor for Christmas tho.
Flashback to Call of Duty 4 Winter Crash where airstrikes would be SantaClaus dropping "packages" from the air
There would be something very wrong sending in a satanic Father Christmas bent on destruction to go raid people's grog and gold. What about turning the thieves into elves, they are small and quick and could easily ransack an island. Or a Rudolph brute who could run amok and flatten buildings.
