[Tactics]

So an AU where Celestial Being got spare drives to develop Double Drive.
Exia and Dynames got the honor being test subject for this new system, come with usual 00 technical explanation and a mysterious MS for next part.

At glance it doesn't look good as Setsuna, Lockon and Ian are just portrait but looking closely this is Sunrise doing R&D of how far they can going with CG.
Its funny how Exia ditches most of its equipment only to use the sword while Dynames just spin beam sword; I always thought the extra arm an unnecessary extension, in practice seems like served as answer to 'how to solve awkward weapons placement and functionality (read: rule of cool)' as you can't pretend it just there like in space setting.
