Chapter Challenge is unlocked once you finish the single-player campaign, and allows you to replay your favorite levels, ultimately measuring your final "Karma" score against other players on a global leaderboard. Ninja Records will supply an exhaustive list of statistics based on your play style -- highest score, largest combo, fastest time, number of sweet guitar solos -- that sort of thing.
In addition, the post reveals the design for the GameStop pre-order bonus costume, the addition of a soundtrack to the game's limited edition, and the second Japanese advertisement for the game, which we've posted after the jump. Sorry to disappoint, but it doesn't contain any plaster lady chests.
