Gundam Breaker plays with scale. This Mobile Suit battling game from Namco Bandai has 1/144 scale Gundam and 1/60 scale Gundam in the same arena.
You can fight on a roulette table and battle players right outside Diver City in Odaiba, the place where the 1/1 scale Gundam stands tall. Gundam Breaker also has a asteroid that looks like the Axis base, a snowy mountain stage, and a jungle area that looks kind of like Jaburo.
Famitsu explains players take on a mission, destroy other Gundam, and then collect parts from fallen Gundam to customize their mecha. Gundam Breaker will have a bunch of mobile suits including:
RX-78-2 Gundam (1/144 scale)
ZGMF-X20A Strike Freedom Gundam (1/144 scale)
GN-0000 OO Gundam (1/144 scale)
MS-06 Zaku II (1/144 scale)
MSN-04 Sazby (1/144 scale)
MSN-06S Sinaju (1/144 scale)
Gundam Breaker is slated for release on PlayStation 3 sometime in 2013. The official site also says Gundam Breaker is coming to Vita, but Famitsu only notes the PS3 version.
