I'm going nuts here trying to remember. I don't know if it was a mod or a full game, you played as Santa Claus gone mad in the north pole shooting everything in sight. You could shoot reindeer and elves (i think) and sometimes a big hard to kill polar bear. You had to collect the heads of those you killed and there was a time limit. I think i played this in early 2000's.

I remember a game like that. The one I had was on a demo/shareware cd that I got with a magazine someone bought me. Can't remember the name, or even the magazine, but I'm pretty sure the makers of that game had made some sort of a hunting game and that Santa Claus fps was made with the same engine.

Man, now I want to see it again :D

It's the one I spoke of, at least. Thanks :)

oh wow that's the one!!
thanks, Google kept giving me flashgames, i started to think i was crazy and that the game never existed.

You can be a GOG.com team member being in Christmas Island?
