Namco Bandai:Gundam Breaker, a new game for the PlayStation 3 and PlayStation Vita systems. This upcoming new game will pit plastic models against other plastic models in stages inspired by diorama. For example, the video shows a 1/144-scale Gundam RX-78-2 taking on a much larger 1/60 scale Gundam RX-78-2. (The backdrop in this scenario is a diorama of Diver City Tokyo — the real-life home of the life-size Gundam statue.)
