Martian Drone

The Martian Drone is a Hardmode, post-Golem flying enemy that spawns during the Martian Madness event. Upon spawning, it flies diagonally up from a bottom corner of the screen, moving through blocks. If not destroyed, it stops once it reaches a point just above the player, and then it spins and explodes into spark particles that fall and linger on the ground, which will damage players or NPCs that touch them.

Tips

 * If the player is inside a tunnel, the drone will stop pursuing and hover on the player's head as long as the player stays in tunnel. The same strategy applies to dealing with Corites.
 * Martian Drones emit a distinctive sonar sound that seems to be audible as long as one is on screen. Listen for this sound so you are not caught off guard.

Trivia

 * This enemy mostly resembles the, a drone used primarily by the United States Air Force.
