The Tundra Storm surrounds Mega Man with a subzero blizzard that damages anything it touches. With the Power Gear active, the blizzard covers the entire screen.
The Tundra Storm is easily one of the most useful Special Weapons alongside the Pile Driver and Block Dropper. The standard shot can reach enemies above or below Mega Man, while the Power Gear version can clear out an entire room and is particularly effective against several mid-bosses.
