Snowball fight was a mode like spy hunt sort of. You can freeze your enemies. If the enemy saves the person forzen, then person frozen can go freeze others. If your teamate or you whacks the enemy wiht a shovel, a few blows and hes dead. Then he respawns, but a team only get a certain amount of respawns until they lose. So if they have like 50 respawns left, if you kill 50 of em by freezing and smashing them, they lose.
