Christmas
Christmas Clique (Left) and Christmas Comet Safari (Right)
Every Christmas, generally during the length of December, the entire city becomes covered in snow. All vehicles will find themselves with worse traction, and snowballs can be gathered from the floor with the G key. These snowballs can be thrown at other players for extremely light damage.
During this time there is a hunt event to find Christmas trees hidden around the map. Hints are given through the in-game Lifeinvader app and the discord #giveaways channel. Only the first person to find each tree gets the prize. These, like all event vehicles will persist through the yearly wipe in late October.
