Bandai released the 1:48 Mega Size Model line in 2009 to commemorate the 30th anniversary of Mobile Suit Gundam. Available in four models - the RX-78-2 Gundam, the MS-06C Zaku II, the MS-06S Char's Zaku II, and the Gundam AGE-1 Normal, these kits are essentially larger versions of their 1:144 HGUC counterparts, but priced much lower than the 1:60 PG line. Once assembled, these models stand 37.5 cm tall (about 15 inches).
Bandai developed these kits with ease of build in mind as they require no tools to build. The individual pieces are attached to the runner by a very thin piece of plastic so that they can be broken off by hand. The assembly process can be sped up even more as the runners have been developed in a way so that you can attach two together and break off the individual pieces that way. Bandai also include a 'Double Separator' tool to help with the new method of building.
The newest model added to this line will be the Gundam AGE-2 Normal, which will be released April 2012. The AGE-2 is the upgraded version of the AGE-1 and will feature the same illuminated head, eyes and chest piece gimmick.
