Requiem flying squid

This flying squid was an alien lifeform living in the jungles of Requiem. It was to be prominently featured as ambient life in Halo 4 during the level Infinity, but the idea was cut before the game's release. It can be seen in various concept art and in the Halo 4 E3 2012 demo build. The concepts had mostly been drawn by Nicolas Bouvier and Paul Richards.
