Martian Madness



Martian Madness is a Hardmode, post-Golem invasion-style event that includes several alien-themed enemies. It can only be triggered after Golem has been defeated.

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 escapes, 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 "" 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.

Martian Madness currently features 11 exclusive enemies and one exclusive mini-boss (Martian Saucer), resulting in 11 different and one trophy.

Tips

 * 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.


 * By using two portals or Teleporters placed about 1000 feet apart, it is possible to quickly despawn regular invasion enemies without progressing the event, giving Martian Saucer more chances to spawn.
 * The Magic Conch can be used to the same effect.
 * due to the laser targeting mechanics of the saucers, staying in one place for targeting and then quickly moving out of the way will result in taking little to no damage.
 * slamming the rockets into the ground with a dash might work if timed correctly and done at sufficient velocity.

Trivia

 * Unlike most other enemies in Terraria, Martians have purple blood when killed rather than red.
 * Martian Madness is one of only two invasion-style events that cannot be manually started by the player, the other being Slime Rain.
 * The name of the event could be a cultural reference to a real-world American basketball event known colloquially as March Madness.
