Alien Machine

The Alien Machine is a Hard Mode Boss summoned with the Alien Pod.

The Boss Battle - First Phase
He has two phases that are very different from each other, In the first phase, he looks like a giant mechanical board with a giant eye in the center. He flies around and shoots lasers out of his eyes, attempting to shoot the player. He also does an attack where his eye starts spinning around, attempting to hit the player.

The Boss Battle - Second Phase
The second phase is completely different than the first phase. It is similar to Skeletron Prime. Once the second phase has begun he will be completely stationary and invincible until two robotic hands attach to him. At first, they are normal hands, but once you kill those, they will become laser cannons. His normal hands will shoot lasers from their palms. The laser cannons will shoot two lasers instead of one.

The Drops
He drops an Alien Circuit Board and an Alien Laser Cannon.
