The Tornadotron was an insanely powerful Saucer Weapon in Destroy All Humans! Path of the Furon. A unique feature was the ability to use it while the Saucer was Cloaked, as stated by Orthopox as an act of God. While even the non-upgraded Tornadotron destroyed about 2 - 3 buildings, a fully upgraded one destroyed an entire town. You held down the fire button and steered the tornado into crowded areas or buildings.
Upgrades[]
The upgrades were the Tornado's Duration (time active) and tornado's intensity (power and destruction).
