Kingdoms of Amalur: Reckoning, arriving on March 20 to Xbox 360, PlayStation 3, and PC.
The content claims to add 15% more space to the overall world map in Reckoning as well, and introduces new enemy types, dungeon areas, and loot. More importantly, though, it introduces Gravehal Keep, a fancy new domicile for your fate-less explorer to, presumably, throw garish parties. No pricing was given for the content, but we'd wager a dollar that it'll cost at least $10 when it arrives later this month.
Update: EA confirmed the price at 800 MS Points/$9.99 across all platforms.
