This is a very similar model of Titan called "Tone" from 'Titanfall 2' videogame.
As you can see from the images, this mecha, is a high articulated model, almost entirely made of 3D printed pieces of a total of 47 pieces that you will mount by yourself.
You will also find complete instructions on how to assemble your little titan
The final result may be different due to the updating of new better files and by your printing, mounting and coloring capabilities.
