Grinding Gear Games has announced (and released) the latest expansion for its RPG, Path of Exile. This expansion, Delve, launched on August 31 for PC, with the Xbox One version coming this week. Path of Exile originally launched back in 2013, t0 a good deal of critical acclaim. Content has steadily released for Path of Exile since, with its last expansion called The Fall of Oriath releasing in 2017.

The new expansion, Delve, brings with it a mission of unending depth. “Path of Exile: Delve features the game’s first infinite dungeon: the Azurite Mine. The mine is filled with treasures and valuable Azurite ore that can be traded in for flares, dynamite and upgrades to your Crawler – a machine capable of piercing the suffocating darkness of the mine,” Grinding Gear wrote. “As players explore deeper into the Azurite Mine, the encounters become harder, with exotic creatures and challenges that are more difficult than any that have been experienced in Path of Exile before.”

Grinding Gear’s co-founder also expressed the developer’s excitement over the new additions to Path of Exile. “Delve is a unique expansion for Path of Exile because it takes player progression far beyond anything we had previously experimented with” said Chris Wilson, co-founder of Grinding Gear Games. “We are really excited to see how players react to some of the surprises that we have buried deep underground in Delve.”

As with all of Path of Exile‘s expansions, Delve is going to be completely free to play and “never Pay to Win,” according to Grinding Gear, as “your success in the game is dependent on the depth of your skill, not your wallet.”

Path of Exile: Delive is available now for Windows PC, and shortly for the Xbox One as well. You can check it out on the Path of Exile website here.
