Irkalla Complex is where the first half of the final Lightfall mission takes place. The first part of the level features Strand grapple traversal across skyscrapers, while the second part is a massive science complex where Calus's siege takes place.
This level was a fun challenge. The rooftop traversal section gives player agency with multiple routes, and the siege defense is one of the first encounters in Destiny to feel like a true battlefield.
I was responsible for the layout, level design, and composition from massout through closing. As always, huge shout to the Palette, Lighting, Vistas, and VFX teams for their excellent work.
