Steambot Chronicles[a] is a 2005 action role-playing game developed and published by Irem Software Engineering in Japan for the PlayStation 2.

She and Vanilla go to a nearby cottage that, as it turns out, holds bad memories for Connie, evidence of this being her in a picture with two unknown figures.

On the way, they encounter a humongous quadruped mechanical fortress (operated by the "Killer Elephants"), which Vanilla must destroy before the trip can continue.

They range from small and speedy but frail, to large, powerful, and sturdy, but slow, but some are perfect in all aspects (Light and Strong and Fast), such as Schneider's and Elder's Trotmobiles, who are the top two ranked gladiators in the game.

Vanilla starts out with a harmonica, and can later acquire the trumpet, saxophone, violin, string bass, accordion, drums, and guitar as well as play church organs and pianos found in bars or colleges.

[18] A sequel to Steambot Chronicles, known as Poncotsu Roman Daikatsugeki Bumpy Trot 2 (ポンコツ浪漫大活劇バンピートロット2, Ponkotsu Rouman Dai Katsugeki Bampītorotto Tsū), was officially announced in September 2006, at the Tokyo Game Show.

[19] Initially the game was designed for the PlayStation 2, with the first trailer showing the new protagonist and a female companion exploring a wintery forest in a Trotmobile before being confronted by larger Trotmobiles, followed by a montage of gameplay elements ranging from downhill combat, fire fighting, loading and unloading ships, and performing in a band.

An issue of Famitsu revealed details that the title moved production to the PlayStation 3 and that Irem would unveil a new trailer at the 2007 Tokyo Game Show.
