Gaijin Games has completed work on its upcoming Bit.Trip Runner sequel Runner 2: Future Legend of Rhythm Alien, and has successfully submitted the game to Nintendo, Microsoft, and Sony for certification.

Gaijin founder Alex Neuse details the experience in this blog post, noting that each submission was plagued with its own unique issues. After squashing some last-minute bugs, however, the team is confident that certification should proceed smoothly.

Gaijin Games' current task is to finish up the Windows, Mac, and Linux versions of the game. If all goes well, Runner2 will launch across all platforms in late February.
