Up until now all of the enemies that have been designed have strictly been ground bound enemies, except some that could leap. This is due to the arsenal that is available to the player throughout early game (not very great at dealing with airborne enemies).
These apparitions are the first of many such upcoming airborne enemies.
I've spent a good chunk of time trying to ensure that the aerial AI motion is up to standard and looks as fluid and believable as possible. That's all for now.
