Stratosphere Base

The Stratosphere Base is the third boss that the player encounters in Iridion 3D.

First Phase
When first fighting the Stratosphere Base, it will shoot one curved line of bullets. This will continue one until the player manages to destroy the phase. It will then proceed to the second phase.

Second Phase
After the first phase has been destroyed, the player proceeds to the second phase. The second phase is more complicated, as it shoots bullets from the sides, rather than from the center. What makes it more harder is the fact that it rotates. Once the player destroys the second phase, the Stratosphere Base is finally destroyed, and the player will earn their bonus.

Trivia

 * This is the first boss that takes place outside of the Earth, in this case, in the stratosphere.
