Cosmic Car Key

Martian Saucer showdown and extraterrestrial tech

The Cosmic Car Key is dropped by the Martian Saucer mini-boss during the Martian Madness invasion with a one in six chance. Defeating the saucer requires evading its sweeping deathray and rocket barrages while targeting its turrets and core. Securing the key rewards players with a miniature flying saucer mount that fundamentally reshapes endgame mobility and world construction.

Infinite omnidirectional flight and hovering utility

Summoning the UFO mount provides infinite hovering flight in all directions at a steady pace of forty-one miles per hour. Because it maintains sustained flight indefinitely without landing, it removes the need to manage wing flight timers or construct arena platforms for bosses like Duke Fishron or the Celestial Pillars. It also offers steady aerial stability for building large structures and sky bridges. However, flying into water, lava, or honey forces an automatic dismount, requiring care near ocean waters and cavern pools.

Trivia

• The UFO mount dismounts instantly whenever the player enters liquids like water or honey, leaving the character submerged.
• Its steady flight speed makes placing long rows of blocks and walls consistent and uniform.
