A new patch update is also out bringing some balances and fixes.
The second part of the Dark Souls II episodic DLC series is available to download now on Xbox 360, with versions for PS3 and PC to follow shortly.
Entitled Crown of the Iron King, the content brings with it new stages, bosses, maps, weapons and armour.
"Beyond the Iron Keep, set in a 'brume tower' covered in soot and ash, players must bare through entirely new hardships," reads the Iron King blurb. "Can you find and recover the lost crown?"
Iron King’s release follows The Crown of the Sunken King which started out Dark Souls II’s crown hunting adventures in July. The final part, Crown of the Ivory King is slated to arrive in September.
Prior to the release of the Iron King DLC a patch update has been made available, including a number of bug fixes and balance tweaks.
