モノリスソフト
First announced in January 2005, the game was never released outside Japan, a fact attributed to the obscurity of some characters and the scale of its script. Releasing to strong sales, the game was given mixed reviews by Japanese and English journalists. Following "Namco × Capcom", Monolith Soft would work on some other crossover titles, including the successor "Project X Zone" in 2012 for the Nintendo 3DS.
