I dont know the actual name of this thing :S, so i named it a Hover Bot.
It took me about 2 and a half hours to make. I made it looking at a screenshot I took from an emulator of Gunstar Heroes.
These often filled the sky on most of the Gunstar Heroes stages and apear Red Green Grey and Yellow thoughout the course of the game.
most of the images are with the Hover Bot looking towards you, as I though the lens would be able to pivot as it also shoots from its lens.
