Obsolete

 Well, not every anime mecha fix is a good one, and this series did barely anything for me.

Drawn in a more western style, this YouTube exclusive consists of 12 episodes of around 13 minutes, and yet if telt like eternity to me, even though general reviews seemingly find it actually a good series.

When aliens arrive in 2014, they just want to trade limestone for an exoskeleton suit, the ExoFrame, which changes the world almost overnight.  Following as such a series of events that teaches how the ExoFrame came into military use, this is shown from various viewpoints and points in time.  And then there is the final episode...

 

But in general... CGI doesn`t work in anime, hasn`t in the past, and it seems it will remain like that for some time still...
