Underwater exploration

Underwater exploration is one of the few systems in AION 2 that the publisher explicitly presents as new to the series. NCSOFT’s official announcement of 4 June 2025 describes it as "underwater exploration, a feature not present in the original" — the phrase "not present in the original" being the publisher drawing the line itself. It is announced in the same sentence as flight, which frames both as parts of one idea: movement in every direction, in every region. What it contains has not been detailed.

The original AION was built around vertical movement upward. NCSOFT’s announcement of 4 June 2025 adds the other direction and says so plainly: "The game offers full aerial freedom in every region, along with underwater exploration", followed by the note that this is "a feature not present in the original". That is the whole of what the publisher has published about it as of this page’s date. No underwater zones are named, no breathing or depth mechanic is described, and no underwater content is listed among the dungeons NCSOFT has announced. This page therefore names the system and stops there.

There is no advanced practice to describe yet, and saying so is more useful than inventing one. NCSOFT has announced that underwater exploration exists and that it is new to the series (official announcement, 4 June 2025), and has published nothing about how it works: no depth limits, no underwater combat rules, no named locations. Any guide that describes underwater technique in AION 2 today is drawing on play reports or on another game. The one structural point that can be made from the source is that underwater exploration and full aerial freedom are announced as a pair, in a single sentence about movement across every region.

The mistake here is one of expectation rather than of play: assuming that because underwater exploration is announced, it is a developed pillar of the game with its own content. The publisher has said it exists and that it is new to the series (NCSOFT, 4 June 2025) — nothing more. No underwater zone or dungeon appears in any NCSOFT announcement this site has been able to date. So treat it as a confirmed capability with unknown depth, and be sceptical of any guide that already tells you how to use it. It costs nothing to plan around, precisely because nothing about it is established. And as on every page here: NCSOFT has not announced what content the Western launch of 30 September 2026 opens with.
