Martian Madness



"Martians are invading!"

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

Martian Madness is triggered by a Martian Probe, which spawns randomly in the two outer thirds of the map horizontally (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 without being destroyed by players, the Martian Madness event begins.

Once triggered, the status message "Martians are invading!" appears, and UFOs start flying in the background (see preview Banner); though Martian Madness enemies will not actually begin spawning until the player is located back at their spawn point. 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 new Martian enemies stop spawning.

Tips

 * You may want to avoid killing smaller enemies to allow more Martian Saucers to spawn during one event, as it has the most valuable drops. Moving to a small arena high enough above the ground makes it easier to ensure no ground-based enemies spawn around you.
 * 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.

Trivia

 * The Tesla Turret is based upon the Tesla Coils, invented by Nikola Tesla, which can look similar and are often used to generate arcing electrical discharges ("artificial lightning").
 * The Martian Walker is a reference to the tripod-like Fighting Machines from H.G. Wells' novel The War of the Worlds.
