Free to play action RPG Path of Exile will have a new league called “Delve” going live today at 1 PM PST. Along with the update bringing new items and weapons, it will introduce the first endless dungeon to the game. Delve will be available in both Standard and Hardcore Leagues.

The “story” behind the new league takes players into the Azurite Mine, courtesy of Niko the Mad. Using a Crawler that keeps the harmful darkness at bay, players will venture into the mine and fight off numerous enemies. Bosses and different biomes await, while you can also use items like dynamite and flares to travel off the beaten path for a short time.

As players progress, the Crawler can be upgraded with different items to make future excavations easier. How far players can progress will ultimately depend on their builds due to the infinitely scaling nature of the dungeon. With 40 new challenges and new rewards to earn upon their completion, there’s plenty of reason to hop back into Path of Exile. The Delve league will go live on both Xbox One and PC.

Grinding Gear Games has finally unveiled its newest Challenge League for Path of Exile: Delve, an essentially infinite dungeon full of tough threats, powerful gear, and much more. Check out the trailer below to see it in action.

Taking place in the Azurite Mine, which has been infested by a powerful darkness, players will move with a Crawler through the mine’s depths. One can choose the path they take, facing powerful encounters and enemies along the way (with some being touted as “much harder” than end-game Maps). Of course, players can travel off the base path with flares, and use dynamite to find hidden rewards.

Azurite located within the mine can be used to upgrade the Crawler, flare capacity, and much more to help venture deeper into the mine. Expect to see different types of biomes as well, with unique enemies and bosses throughout, some of them being essentially “lost cities” from Wraeclast’s past.

The Delve League will also see ten new/reworked skills for the Guardian and the Pathfinder, along with new items, improvements to the graphics engine, and much more. It goes live on August 31st, so if you’ve yet to complete the Incursion League, get on that quick.
