Desktop/Console/Mobile-Only Content: This information applies only to the Desktop, Console, and Mobile versions of Terraria.

The Martian Saucer is a large flying Hardmode, post-Golem mini-boss that spawns during the Martian Madness event. It can only spawn if the Martian Madness event is 30% completed or higher, and it can move through blocks. It has four turrets with independent health meters that each must be destroyed, which include two rocket launchers and two laser machine guns. In addition, the Martian Saucer itself fires a "Martian Deathray", a large yellow beam that can only be fired directly downward and cannot be destroyed independently.

Behavior

Upon spawning, the Martian Saucer cycles through three different attacks that are performed in the following order. In between attacks, the Martian Saucer will move a short distance toward the player.

If at least one Martian Saucer Turret is still active, the Martian Saucer remains stationary while its turrets rapidly fire a volley of yellow lasers at whatever location the player was before the attack was initiated for about 2.5 seconds.
If at least one Martian Saucer Cannon is still active, the Martian Saucer remains stationary while its cannons launch several homing missiles that explode upon contact with the player or solid blocks.
The Martian Saucer positions itself above the player before unleashing a Martian Deathray from underneath it while traveling in the direction the player is currently moving for 4 seconds.

All four weapons must be destroyed in order to defeat the Martian Saucer. However, upon destroying each of the Martian Saucer's turrets, destroyed sections are replaced by unprotected gaps of exposed wiring. The usual projectile attacks of any destroyed turrets will be replaced by those sections releasing sparkling Saucer Scraps, which fall to the ground, linger on solid tiles for several seconds, and damage the player upon contact.

In Expert Mode and Master Mode, instead of being defeated immediately after the destruction of its four turrets, the Martian Saucer enters its second phase, which exposes its core component and causes it to jostle violently for several seconds before continuing to pursue and attack the player. During the second phase, the Martian Saucer attempts to position itself above the player to their left or right before sweeping towards them while firing Martian Deathrays, which pass through solid blocks and deal significantly large amounts of damage. The Martian Saucer alternates between positioning itself to the player's left and right between deathray attacks while its four exposed sections continuously release Saucer Scrap projectiles. Upon depleting the health of its core, the Martian Saucer will be defeated.

Notes

If the Martian Saucer is transitioning into its second phase during its deathray attack, the deathray will stay in one place until the transition is complete.
Killing a Martian Saucer adds 5 percent completion to the event.
The Radar and its upgrades counts the Martian Saucer as 6 enemies total: one for each turret/cannon, one for the Martian Saucer Core, and one for the large invulnerable piece.
The Martian Deathray may appear to be unable to pass through solid blocks (the ground, for example), but it can shoot through solid blocks to reach the player. This functions similarly to the Moon Lord's Phantasmal Deathray.

Tips

For more elaborate strategies on defeating Martian Saucer, including weapon and arena recommendations, see Guide:Martian Madness strategies.

To dodge the Martian Saucer's first attack, hover above or below its lasers. To dodge its second attack, run away from it as it shoots so that most of the missiles hit the ground in front of the player.
To avoid getting caught by its deathray, fly over the Martian Saucer or dash away or use the Rod of Discord or Hook of Dissonance. During the second phase, move counter to the Martian Saucer's movement during the pauses in its deathray. With well-timed dashes, the deathray can be completely avoided.
When the Cute Fishron's "wet" bonus is activated, the player can fly slightly faster than the Martian Saucer.

Trivia

The Martian Saucer is a unique mini-boss in several ways:
- It is the only mini-boss that has a status message that appears in the chat when defeated.
- It is the only mini-boss to drop recovery potions.
- It is categorized in the Bestiary as a boss.
The Martian Saucer is one of three bosses with a corresponding minion (Xeno Staff), the others being The Twins (Optic Staff) and Duke Fishron (Tempest Staff).
The Martian Saucer was once named "Mothership" during development, according to an unimplemented achievement.

The Bestiary entry for the Martian Saucer: "An advanced flying saucer from somewhere well beyond this world. The destruction from its weaponry is unimaginable."
