Darksiders II: The Demon Lord Belial DLC will be released today, worldwide on PC and Xbox 360, and in North America on PS3. European PS3 gamers must wait until tomorrow.

It transpires that the Third Kingdom was not completely destroyed, and remnants of humanity survive. It falls upon Death to seek out the truth and unearth a forgotten evil... The Demon Lord Belial.

The Demon Lord Belial is priced 800 MS Points / $9.99 or is offered for free for those who have purchased the Darksiders II: Season Pass. There's no mention of the DLC making its way to Wii U.
