Very huge box indeed. But being a variation of PG Strike, I doubt that it's any bigger than its box size.
The booklet on the bottom right should be the prize included (both versions).
Die cast pelvis and knee joints - molded in red.
The reused runner from Strike, which includes parts for the waist that is not necessary ^^;
Love the zigzag design of the katana's handle. ^^
The katana has a protective sticker at the edge.
From the images of the runners posted, one can spot a few of them are reused ones from PG Strike. Large numbers of parts for the arm and legs are from that previous release.
