The Saucer was equipped with Weapons of destructive fun that were used to wreak havoc on Humans. The Saucer's internal structure also changed color when it changed weapons.
Lethal Weapons[]
Death Ray: The primary weapon that was used throughout the series. The Death Ray had formidable power even when it wasn't upgraded. It leveled buildings and incinerated enemies. Most, if not all Furon Saucers had that weapon at the very least. No ammo was required, but it needed time to cool down.
Sonic Boom: A very powerful shock wave generator that required ammo, was quite useful to level buildings faster, and required 1 or 2 shots to demolish a normal one. It was even more useful for battling large enemy patrols such as tank columns.
Quantum Deconstructor: The Saucer's most powerful weapon in the Destroy All Humans! series, which, in the past, required ammo, but in 1975 it recharged on its own, and in 1977 it charged manually for customized blasts. According to an in-game description, the Quantum Deconstructor created a “thermonuclear cloud.”
Anti Gravity Field: A great disabler. It fired a black energy ball that, once landed, sucked in enemies and vehicles, and kept them in mid-air for a short period until the ball imploded and caused blunt force trauma.
Electro-Cone: Created an electric field around the Saucer and struck lightning at objects underneath at rapid fire. The Electro-Cone went off a battery charge that was similar to the Zap-O-Matic.
Seeker Drones: Acted as homing missiles. When a target was locked, the Seeker Drones launched and destroyed the target with no questions asked. It was quite useful against flying enemies, changed the new Saucer's color to yellow, and glowed bright when it was in use.
Plasma Cannons: A dual pair of powerful plasma energy-firing auto cannons, which was useful on both ground/flying enemies and buildings. It changed the Saucer's color to purple, and glowed pink when it was in use.
Tornadotron: A formidable weapon in Path of the Furon which generated a tornado, which you could steer, and could be activated even while the Saucer was Cloaked (which made humans think that it was an act of God). The Saucer's color changed to a light blue and glowed white when it was in use. It leveled buildings and anything else that was in its way. It was so powerful, that it was the only weapon that could destroy an entire town/city in one shot.
Non-Lethal Weapons[]
Abduction Beam: Used to abduct humans for DNA gathering. In the past, it was used to pick up the needed individual humans one at a time. But in later years, it acted as a vacuum to suck up large groups of humans, and also worked on vehicles. It was extremely useful for tossing tanks and other heavy veins into bodies of water.
Drain: Part of the Abduction Beam's function which was used in Destroy All Humans! 2. It repaired the Saucer from critical damage, reduced the victim to dust upon full completion, and only worked on vehicles.
Transmogrify: Another function which was first used in Destroy All Humans! 2 to regain more ammo. It functioned in the same way as the above tech.
Cloak: Rendered the Saucer invisible for a short period of time. In later years, it was upgraded to last longer.
Jumbo Probe: Used as an instrument of extreme torture in the original Destroy All Humans!
