The Air Saucer is a one-manned floating black disk with a red trim on the outer rim of the disk. It features six blades that rotate when in use. According to E-123 Omega, they float without using thrust or engine components.
In Shadow the Hedgehog, the Air Saucers are used primarily by the Black Arms to cross hazardous surfaces such as lava or acid. It is damaged by enemy bullets and by bumping into walls and obstacles. They are commonly ridden by Black Assassins and are mostly seen in Black Comet stages.
Shadow can jump on and commandeer an Air Saucer if he can defeat the Black Arms riding it. With it, the player can cross fatal liquids which flow through the levels. While the player can make the Air Saucer jump, it cannot reach as high as Shadow's Spin Jump though the player can perform a Double Jump. Making contact with a weapon while riding an Air Saucer will cause the player to immediately take it, even if they already had a weapon.
