Now I have a machine gun. Ho Ho Ho.

You know what I've always felt Christmas eve lacks?
Paranoia and a sense of impending doom.
The "party game" I just picked up should do the trick.
Each player gets a Nerf gun, the name of a target and the location in the house where they have to shoot them at some point over the course of the evening.
Nothing says "Christmas" like an assassination contract.

.....yes. I have been playing Hitman too long.
