Zangeki no REGINLEIV is an up and coming game published by Nintendo and developed by Sandlot (Earth Defense Force series). The game promises epic battles featuring mammoth-sized monsters and foes. The game is notable as it's the first Cero D-rated game from Nintendo in Japan as far as I'm aware of. Please correct me if I'm wrong, but first, watch the immense sense of scale you'll get from the many enemies the game throws at you. Here's hoping for a North American release.
