The levels I had responsibility for was 1th, 2nd, and 4th. The 4th level was the last level, we wanted that level being the most rememberable one in the game. I thought of a way to re-use mechanics in a new way to add a unique element to the last fight. I asked the artists to divide the last enemy structure into 3 mesh layers. I made them into separate entities so they could be destroyed individually.This meant I could have different phases during the boss fight, when one part of the structure was destroyed I could trigger any event I wanted. A feature that was added the last days was allied ships, I made the whole boss fight revolve around allied reinforcement and taking down the structure layer by layer.
