It includes the Golden Tower, which can fire missiles and the upper room can come off. There is a trapdoor is the roof and you can fire flick missiles out the front door; and the Sonic Raven, which is controlled by Devastator has two missiles and spinning blades. It also includes some swords so that Hitomi can defend the Golden Tower.
An alternative model showed up on the official website but was never named.
The alternate model only consists of pieces of the Tower. The Sonic Raven does not have to be taken apart.
The golden tower is the tallest building in the golden city, and houses the massive computer that is the central knowledge storehouse. It is here EXO-FORCE pilots bring the codes they have retrieved for entry into the computer. It is also in this tower that Ryo, Takeshi and Hikaru received their new battle machines. Due to the importance of this structure, it is guarded night and day. Hitomi is posted here in the set, armed with two energy katana.
