The generic model has been updated to blue (who'da thought) and a working Mega Buster is created! The shots were made to track enemies, up to a specific angle (max angle presented here). It should make targeting far enemies easier without needing a lock on. Enemies can of course move out of the way depending on the distance. For the time being, 15 degrees seem to work, but trial and error will be applied.
As a reference, here is a straight shot from the same position and direction.
(also added a motion blur)
