Described by Q-Games President Dylan Cuthbert as "a bit of fan service," 2nd Lap will include all of the content in the original downloadable game while adding trophy support, easier difficulty levels, and "ghost attack" races in which you can race against recordings of the top scorers on each track. According to numerous reports about the game coming from GDC (from the likes of and ), 2nd Lap will be available for owners of the original PixelJunk Racers for a nominal upgrade fee, while new racers will spend a larger amount that has yet to be determined.
