Invincible Battle Fortress (Qiji 2317)

About this set

KEEPPLEY 2317 The Battle Bunker sits in the Castle series, with 1541 parts on the box, a 6+ age mark and a 2/5 difficulty score. It is a medieval fantasy castle build in grey, blue, gold-yellow, brown and green, and the finished model includes a main keep, folding walls, a catapult, a chariot, a gate, a water wheel and minifigures. The selling point is the 2-in-1 direct transformation: fold the keep joints and merge the two side walls to switch into the invincible chariot form. For the build order, assemble the keep joints and each side wall as separate sub-builds before joining them, otherwise you risk pulling parts apart during the merge. Save the catapult, chariot and water wheel until the main body is done so you can adjust their positions, and place the minifigures last around the gate and walls for a siege scene. With a 2/5 difficulty, a 6+ kid can handle most of it alone, with a little help lining up the joints and walls. It suits builders who want a medieval fantasy castle they can transform and handle, and the grey, blue and gold colour layering still reads well as a display set.
