Holiday Havoc is a secret battleground in Twisted Metal: Small Brawl. It is unlocked after getting 30 kills in Endurance Mode.
The battleground is an interior of a house with a Christmas tree with presents under it, a train on a track going around the tree, a sofa, a lamp, present ramps, and Santa Claus stuck in the chimney.
- You can shoot the train to get Health pickups.
- Drive behind the sofa for cover if you are low on health.
- Players can shoot Santa in the chimney. However, players don't get anything.
- The sofa can be destroyed simply by driving into a part of it, or shooting.
- The music track to this stage is a remix of the Stalk 'N Roll track from Twisted Metal (1995).
