The charged shots on the catalyzer lines have a large impact on the weapon, and the timing of the blasts. Both neutralizer and biohazard charges move counter clockwise. Make one circle clockwise, and the other counterclockwise. I would also like to suggest making the angle of the bullet start at where it hits, rather than facing straight north at the start, regardless of the angle it hit at.
Not the most necessary of changes, but would be an interesting tweak.
Umm why?
