Path of Exile is the game which gets constantly upgraded or reworked in various ways. For example, last year the developers basically doubled the length of the main story, and now Grinding Gear Games reconstructed everything else, basically making a completely new game, concerning the content that is not part of the main story.
The biggest addition to the side quest mechanic is the introduction of The Betrayal League, which is the name for the organization of immortals that you have to teach a lesson or two about the repercussions for double-crossing the wrong people. This gameplay mechanics seem a lot like Shadow of Mordor. Another prominent change is noticeable when you’re about to get your quests from The Forsaken Masters, which is a pantheon of ascended beings that grant assignments to the hero of the game. You might notice a new set of faces, each of them giving you some new optional errand.
This expansion is really, well, expansive. The patch notes only are 8000 words long, with a full table of contents. Similar to the previous three quarterly leagues, the centerpiece of this expansion is a new organization and a side quest campaign which revolves around them. Your mentoring character is Jun Ortoi, and she wants you to defeat the Immortal Syndicate, an organization consisted of immortal evil-doers. Your goal is to reveal who is the leading figure of the organization and dispose of them by infiltrating the Immortal Syndicate and set up their leaders for conspiration against their leaders. After you seize the betrayer, it’s up to you what to do with them. Depending on your action you can get new information, get reassigned or even promoted.
However, there is one big difference between this expansion of the past ones: This time, Jun isn’t leaving after 3 months, but he joins the other past three League representatives in the group that completely replaces the Forsaken Masters. Although Jun is the main quest giver, Niko, Alva and Einhar will also provide you with some hefty optional tasks. The endgame is now expanded by challenges given by them, but that’s not nearly all.
Except for the tremendous auditions in the quest department, there is also a pile of new loot to find, skill gems to use, and some balance tweaks. The hideout system has been overhauled too, given that the new quest givers don’t have reputation grinds attached. As you explore, you will find new hideouts in form of rare mini-dungeons. There are also some tweaks for the crafting system. Now everything’s done from one table, and you can unlock additional recipes by completing specific challenges, or by Jun revealing new item modes.
All these additions are live now, including The Betrayal update and new League. Be warned though, it’s a big download. On Steam, it weights some 8 gigabytes, and it’s 4,5 GB on Grinding Gear’s own client. It is considerably big, but concerning how many new things it brings to the Path of the Exile, it is justified.
