Path of Exile's The Fall of Oriath expansion is set to launch on 4 August 2017 with six new acts and expanded character customisation. It's all still free, but early beta access is only available to supporters, unless you get lucky and get selected for beta testing at random.
Path of Exile: will be launching on PC in two weeks with the same content arriving on Xbox One soon after. The expansion will add refurbished versions of previous acts to the game, along with the ability for players to wield the power of the Gods, which probably refers to added character customisation options.

Usually, Path of Exile is free to play, and the expansion content probably won't deviate from the so far quite successful formula, but anyone interested in a definite spot for beta testing will only be sure they get in by purchasing one of the game's supporter packs.
Grinding Gear Games will be sending out beta participation invites for the upcoming Xbox version of the same expansion in waves, and will be doing so at random when it comes to player selection.

"The Fall of Oriath is our largest content expansion ever. In addition to six new acts of content, it includes new skill and support gems, unique items, our new water renderer, improvements to world environments, the minimap, game performance, and much more", was announced by the studio.
Path of Exile is a free ARPG for which a lot of people claim that it's the Diablo 3 they never got, so you can have a look at what all the fuss is about with loss.
