In honor of the 15th anniversary of the WEAPON UNIT series, several units in the lineup will be undergoing an upgrade. In place of the shield that is no longer in production, a large-sized shield with expansion capabilities, Multiple Shield, will be joining the lineup instead. Each part of the Multiple Shield can be separated or attached using the 3mm connection points. The back of the shield is equipped with multiple hard points, allowing users to attach included parts or separately sold Weapon Units. The included handgun and knife can be attached to the 3mm connection points using the included attachment parts.
