Martian Madness is triggered by a Martian Probe, which spawns randomly in the two outer lateral thirds of the map (with a higher spawn chance in the Space layer). When this small flying enemy detects a player or is attacked, it immediately attempts to fly away. If the Probe is allowed to escape and despawns off-screen, the event starts. This requires at least one player with at least 200 maximum health to be in the world – otherwise, the event will not start.
Once triggered, the status message "Martians are invading!" appears, and UFOs start flying in the background (as seen in the banner above); though Martian Madness enemies will not actually begin spawning until the player is located near the default spawn point or near an NPC with valid housing. As with other invasion-style events, a progress bar is shown in the bottom right corner while the event is ongoing. This bar fills as event enemies are defeated. When it reaches 100%, the event ends and Martian enemies stop spawning.

Notes[edit | edit source]
- A Martian Probe will not spawn if the Lunar Events are active, if a Martian Madness event is already started, or if another Martian Probe is currently already present anywhere in the world.
- After exiting a world during a Martian Madness event, the screen in the main menu will have Martian probes flying around.
- While playing in Expert mode does not increase the drop rate of Martian Madness items, it does increase the spawn rate of the Martian Probe.
- It is possible to override Martian Madness with the Pumpkin Moon, Frost Moon, or other events.
- Exiting the world just before the Probe despawns may prevent the event from occurring when it is re-entered.
- Martian Saucers are much more common after 50% of the event has been completed.
- Event progress is saved when exiting the game.

Tips[edit | edit source]
- Martian Madness is one of the more difficult events to have occur, due to the fact that its summoning requires a random spawn of a Martian Probe. However, with a proper spawn platform or via the use of a Floating Island towards the outer thirds of the map, it can be "summoned" more easily.
- If the Martian Probe has detected a player, chasing it might cause it to despawn, thus care should be taken.
- While most minions will not deliberately target the Martian Probe, some can still accidentally kill it before it has the chance to detect players and escape, preventing the event from triggering. Minions should be dismissed if the player is trying to cause an invasion to occur.
- Since the Martian Saucers drop the most valuable loot out of all enemies, it is usually preferable to allow as many of them to spawn as possible. Moving to a small arena high enough above the ground makes it easier to ensure no ground-based enemies spawn, increasing the chance of a Saucer to spawn.
Trivia[edit | edit source]
- Unlike most other enemies in Terraria, Martians have purple blood when killed rather than red.
