Snow is a rarely featured weather pattern in GTA games. The snow feature is available in the PSP version of GTA Liberty City Stories. If the player continues the Car Salesman missions after level 6 and reaches level 9, a snowy weather effect starts to appear and continues appearing in further levels. This is possibly there to make driving more difficult. The snow will disappear if the player fails or cancels the mission, and Car Salesman cannot be played again afterwards, so you can only see this once. This weather effect does not appear in the PS2 version of the game.
- Snow is technically already in Liberty City, as seen in the mission Saint Mark's Bistro in Grand Theft Auto: San Andreas.
