Now this a really cool SD kit!
With these kits, it seems that Kotobukiya wants to reproduce how the mechas look in the latest SRW OG game and I think they nailed it, this Alteisen Riese looks like it came straight out of the screen.
As usual, there are a ton of parts for each component of the model, however, color separation is not as good as I expected, you will need to do plenty of touch ups everywhere with black, white, yellow and gray paint, far more than those required for its older 1/144 counterpart.
Regarding the articulation, while it has double jointed (!) elbows and knees, the lack of a second balljoint in the torso allowing the model to do a forward crunch severely limits the poses you can get with the mighty brick. Nevertheless, that is not an issue, as I will display it using the claymore attack effect parts, which also require some paint, but I bet the final result will look awesome.
I also still have to finish the backpack and the wing binders, but those will be a breeze.
