Refusor

The Refusor is the first boss that the player fights in Iridion 3D.

Boss Battle
Unlike the Main Frame, the Refusor has more defense, as well as bombs that can powerfully damage the player. The main weak spot is the green cylinder that the player rotates around. However, it'll close and shoot out bullets. It then repeats itself, thus allowing the player to know its movements. Once it's fully destroyed, the player achieves victory and he/she proceeds to the second stage.
