The snow feature is available in the PSP version of GTA Liberty City Stories. To acquire it, the player has to complete level 9 of the Car Salesman mission in Portland. The player must complete all levels without failing because after level 6, the mission is technically over. The snow will end as soon as the player ends the mission.
- Snow is technically already in Liberty City, as seen in the mission Saint Mark's Bistro in Grand Theft Auto: San Andreas.
