Grinding Gear Games has released its first massive expansion for action RPG Path of Exile onto Xbox One.

War for the Atlas features 32 new randomised maps and a host of new challenges and rewards as players find themselves caught between two powerful entities battling for the control of Wraeclast – The Elder and The Shaper.

As these maps are completed, the Atlas is altered to show who is in control. As The Elder grows more powerful, he consumes The Shaper's creations to manifest his own Guardians.

So, if the scales are tipped in favour of The Elder by the player's actions, it can appear on the map briefly to usher in a special event.

War for the Atlas contains more than 50 new Unique Items, 10 new Gems, and four new necromancy skills.

"These are some of the most difficult battles ever and everyone's war is different. You decide what's best for you in terms of what items you want to fight for," Grinding Gear Games founder Chris Wilson told MMO Bomb.

Path of Exile: War for the Atlas launched for PC on December 9.
