Snowball Fight was a stupid game mode anyways because it was so easy to powerlevel...
The only thing I don't get is why my player profile on Nexon still says Snowball Fight on it if that mode no longer exists.
On nexon's website it was listed as an 09 event, but still no-body knows.
There is a scheduled patch for the 3rd.
Don't get your hopes up, but that patch has been postponed for a while.
I myself haven't tried it, I wouldn't mind giving it a go.
Err...Snowball Fight was during December '08 - Feb '09 if I recall correctly...
I had a friend who powerleveled by exploiting the game mode, and he got an account reset in the end, so it was not worth it.
The new patch I've heard includes a new map...hopefully its not a crappy map like Roadkill.
