- ―Official Description
Whirlwind is an Uncommon Autocannon in Fortress: Destroyer. One of the most powerful weapons in the game, despite being Uncommon, and it can reach a very high DPM; up to 30,000+ with sufficient modules and grade. Though this weapon is high level, it still comes standard on your first Battlecruiser.
