How do I create a circle of bullets?

Im making a game where the core mechanic is a circle of bullets going out of one point. I don't know how to make this, I've tried to make it so that the center object rotates every "x" degrees and it spawns a bullet but it creates a swirl pattern. Any help will be greatly apreteated.

Use a For loop that creates your bullets (sprites with bullet behavior) and set the angle of motion by multiplying with the loopindex.
