Medalots (components) and medals featured in "2" have undergone significant changes, with the previous Medalot and its successor now restricted to those used by specific characters and the hidden Medalot from the prior game. Meanwhile, new abilities such as first aid and posture disruption have been introduced, and the variety of parts has expanded considerably compared to the previous installment. The narrative takes place in an underground city, an undersea city, an aerial city, as well as the universe and the moon. The story remains central to the series, exploring the origins of the Medalot.
