Kara comes in four pieces plus the base - Body, right arm with gun, left arm with sword, scabbard.
The assembly is extremely straight-forward - the gun is a very secure fit, contacting the model on the back (with a location lug) as well as the shoulder. The sword can be positioned in a few different ways, to give some variation from the studio version shown in the game. The scabbard is a simple plug-fit piece.
