Steambot Chronicles 2 (AKA Poncotsu Roman Daikatsugeki: Bumpy Trot 2 in Japan) is a cancelled steampunk sandbox / action mech game that was in development for the Playstation 3 by Irem, originally announced on September 2006, at the Tokyo Game Show. Steambot Chronicles 2 was officially canceled along with several other Irem games following the Japanese tsunami / earthquake in march 2011. It’s possible that Irem had already some problems with the development of Steambot Chronicles 2 and the natural disaster in Japan was just the nail in the coffin for this interesting project.
As wrote by Tollmaster on Mecha Damacy:
it seems that the original Steambot Chronicles is doomed to remain a one-off work of genius, an inexplicably deep and mold-breaking PlayStation 2 game where players finally got to see the civilian side of mecha. There was a living, breathing world outside the game’s mechanical boss battles and pitched tournaments; loading up lumber on your clunky steam-powered robot’s flatbed to help construct a bridge in-between playing the harmonica in a touring band and helping root out vast conspiracies seeking to control the world’s oil supply immersed you into something deeper than any other game has ever hoped to.
