I picked up the Clone Wars version of the Gun Ship for $29.99 at Toys-R-Us today here in Indianapolis, IN.
Being a fan of the Gun Ship I decided to buy one. The funny thing is that TRU has the older GunShip on the shelf for $44.99 and the new Clones Gship for $29.99.
Anyways the new release of the GShip is the exact same as the other GShip just re-painted. Where the "Added More Fire Power" is I do not know.
This is prett neat, the GShip has kill markings on the side.
Gun Turrents are from the Clone Pilot Figure. The Ship does not come with them.
