The next Path of Exile expansion is the game's biggest yet, says developer Grinding Gear Games.

The Fall of Oriath will add a fifth act to the free-to-play Kiwi action-RPG, and remix the existing four to create a new game experience.

That means rather than having to repeat the game's first four acts three times to get to its Atlas of Worlds endgame, you can play through the first four acts, act five, and then the first four remixed (as acts six through 10) to get to its end game content.

Act 5 returns players to Oriath to seek retribution for their exile. It includes new skill gems, unique items, 24 bosses, and more.

Some of the new bosses are gods, and they introduce a new Pantheon character customisation system to the game: you kill gods and are rewarded with upgradeable passive abilities.

As per GGG:

Atop the frozen peaks of Mount Veruso lies a way to return home, but the death of Dominus has left Oriath in turmoil. Caught amidst the slaves revolting against their Templar oppressors, you are all that stands between the innocent lives trapped in Oriath the divine wrath of High Templar Avarius.

Once players complete the new act, they will be able to play through reimaginings of the first five acts, but with new NPCs, quests and some layout tweaks.

GGG, again:

Your triumph over the Beast has had unforeseen consequences. The dormant gods of Wraeclast, once suppressed by the beast, have regained their divine powers. In Part Two, a set of five new Acts, you will weave through both new and recognisable locations throughout Wraeclast, witness the results of your past deeds, and even confront the gods themselves.

Full details are expected in the coming weeks, but for now you can check out the official page for Act 5.

Act 5 will go into beta in late April/early May before a full release in June or July.

"It has been so hard keeping the secret of the five additional acts from the community," GGG founder Chris Wilson told us.

"They knew we were working on one new act, but had no about that it was a total of six in development. We can't wait to see what they think when they get a chance to play them!"

Path of Exile has seen astounding growth recently. Grinding Gear added two expansions to the game last year, and it boasted one million active players in December. In 2016, the game's total playtime was up 44 percent on the previous year.

Grinding Gear Games is working with giant publisher Tencent to bring the game to the Chinese market. Path of Exile is also coming to Xbox One this year.
