How to find Martian Probe in Terraria
Martian Probe is commonly found in the outer two-thirds of the map, i.e., the space layer. Besides this, players can also use items like Water Candles triple the Martian Probe’s spawn chance. They can summon above the maximum player height; hence they can detect the player without being noticed.
