Falling robots

 are enemies in Bullethead. They are a Metal head with 2 Green Eyes and 3 small antennas.

Attack
They come from the sky in a row that goes across the screen. They will first fall then stop at a bit lower then the top of the screen, then fall. When they hit the ground, they all explode. The can come in rows of 1 to 7. Sometimes, the Falling Robots will continue to fall, and keep respawning what they had left, forcing the Player to eliminate all of them.

Trivia

 * The reason the Falling Robots can be killed so easily is that if there health is higher, it would be impossible to kill them before they hit the player.
