Terraria Wiki → Martian Invasion
Martian Madness is an event added in update 1.3. It can be triggered by killing the Golem.
General Information:
The Madness begins with the appearance of a Martian Probe (for more information on how to summon it, see the notes here), which scans you and, after completing its exploration, flies away. The event can be prevented by destroying the probe or running away from it before it notices you.
After the event starts, the message "Martians are invading!" appears in chat, and flying saucers begin to appear in the background. However, the event agents themselves (as with the Goblin Invasion and Pirate Invasion) will only appear in the central part of the map.
All event agents, except the flying saucer, turret, and drone, have a chance to drop Martian Conductive Plates (8-20 from a single enemy). Banners can also be dropped from each enemy except the flying saucer.
Event Representatives:
