Martian Madness is one of many exciting events you can trigger in Terraria after meeting some requirements. It’s critical to face waves in this invasion as you’ll get useful items such as Xenopopper, Charged Blaster Cannon, and Xeno Staff. After all, facing four Celestial Pillars can become a nuisance with outdated gear.
In this short guide, we’ve shown how to trigger the mentioned event. We’re also including notable loots.
Martian Madness in a Nutshell
This event consists of Martian Saucers and Scutlixes, to name a few aliens, invading your world. Like the Goblin and Pirate Invasion, killing enemies will fill up the progress bar until 100%. After that, aliens will stop spawning.
The invasion is one we recommend facing before progressing further in-game. Items you’ll get are great before facing the few final bosses in Terraria, especially if you’re on a harder difficulty.
How to Spawn the Martian Madness
To activate the event, make sure to meet the following requirements:
- Let the Martian Probe escape after detecting you. The Martian Probe is a jellyfish-like robot, emitting green scanners similar to a Wi-Fi icon. The scanners will turn red if it detects you and then attempts to leave. You can find this entity in the outer two-thirds of the map on the Sky and Space layers. We recommend equipping the Lifeform Analyzer.
- 200 total HP.
- Go near any NPC with a valid housing or the spawn point.
- Golem is defeated.
The Martian Probe is a rare entity. As initiating the event is important, using a Water Candle and Battle Potion will increase the spawn rate. If any other invasions occur, skip the day/night before approaching the entity.
