Origin
There are numerous references to the Star Fox series in this level. Commonly seen ships in the game, the Wolfen and Arwing, can be seen in the background. As mentioned earlier, Sector Z is a level in Star Fox 64, the fifth level when taking the hard path. The level takes place in a nebula en route to Venom when the Star Fox team and the Great Fox are ambushed by Andross' fighters who have a weapon never seen before, missiles. These missiles also appear in the background of the stage. The player must protect the Great Fox in this level from enemy fighters and missiles hits. Sector Z was also a multiplayer level in Star Fox 64. This area was probably chosen for the setting of this stage because it is the only stage where the Great Fox is prominently seen in its normal form and the Great Fox acts as a great platform.
