This MMO's New Zone Is 2,000 Meters Tall, From Sunken Ruins to Cities in the Clouds. Riot Just Handed Traversal to a WoW Veteran.

What Happened

An MMO just shipped a zone you measure in meters of altitude instead of square kilometers, and it did it seven weeks after Riot put world traversal on one designer's desk.

Everstone Studio and NetEase have dated Hidden Mountain, the expansion that opens Where Winds Meet's Version 2.0, for July 23 UTC. The developer letter published July 19 puts a number on the part that matters: vertical exploration depth beyond 2,000 meters, spread across 4 main areas and 14 sub-regions.

The stack runs from underwater Mohist ruins and subterranean labyrinths, up through the mountain, to cities suspended in cloud. You move between those layers with Lightness Skills, climbing, gliding, and mechanical vehicles you craft yourself. That last one is the tell. A studio doesn't put player-built vehicles in a patch unless the map is big enough vertically that walking stops working.

The rest of the update is sized to match. A new faction called the Mohist Hill Sect arrives built on engineering rather than martial arts, set against the Qiongqi Artificers. There's a Divinecraft quest series, a Celestial Seize ability for manipulating mechanisms and terrain, and a Modulating Stone system that salvages spare Legendary gear. Gauntlets and the rope dart come in as weapons, plus a combined style called Bamboocut Kite. Clockwork bosses ask you to solve environmental puzzles mid-fight. Everstone says more than 10,000 interactive NPCs run daily routines in the region, and the whole thing lands under an "Eastern Steampunk" banner alongside a 2.0 visual overhaul.

The Details

What This Means for the Riot MMO

In June 2026 Riot hired Brian Holinka onto the MMO as Principal Game Designer. Press reporting on that hire was unusually specific about the remit: player combat, world traversal, enemy behaviors, and core character actions including camera control and movement feel. Traversal isn't buried in that list. It's a named pillar with a senior name attached. That same hire was worth reading a different way just yesterday, when Throne and Liberty turned PvP into seasonal matchmade 12v12 and put the spotlight on his combat and PvP record instead.

So Hidden Mountain lands at a useful moment. It's the clearest live demonstration this year of an MMO treating verticality as the content rather than the backdrop, and it ships the movement kit to go with it. Climbing, gliding and player-built vehicles were designed together, because a 2,000-meter zone falls apart if they weren't. Verticality is a traversal problem long before it's an art problem.

Here's why that should interest anyone watching Riot. Runeterra was written to demand exactly this, and it was written that way years before anyone had to build it.

Targon is a climb, and Riot has been drawing it that way for a decade

Targon isn't a mountain in a skybox. The region is an ascent with a gate at the top. Leona and Diana are defined by which celestial power met them up there. Pantheon is what happens when someone reaches the summit and something comes back down wearing him. Taric climbed it and was remade. Aphelios and Zoe both hang off the same vertical cosmology.

Look at Riot's own region art. This is not a studio that drew a mountain and moved on. It drew the gear you'd need, the road up, the settlements on the ledges, and the weather changing as you gain altitude.

Every one of those pieces is a traversal brief. Climbing gear implies a climbing system. A vaulted road implies a critical path with shortcuts off it. Settlements on a cliff face imply hub design where the neighbor above you is a rope away instead of a jog away.

Piltover sits on top of Zaun, which makes it two floors by definition

Piltover and Zaun are the other case where the geography has already made the decision. Piltover is above. Zaun is below, in the fumes. Jayce lives at the top of that stack and Ekko lives at the bottom of it, and Vi is interesting precisely because she moves between the two. The elevator, the descent, the difference in air, all of it is already canon.

Hidden Mountain's craftable vehicles are worth staring at here. They're a crafting sink that doubles as exploration content, which is a shape Hextech and Zaun chem-tech could take without anyone squinting. That's also the kind of system that has to respect the setting instead of overwriting it, a line Stars Reach walked straight over when it shipped sliders for everything.

Shurima's best-known moment is a Z-axis event

Shurima is buried. That's the premise. And the cinematic Riot built to establish the region is, structurally, a traversal sequence: it spends almost its entire runtime underground before it goes up. Azir is resurrected in a ruin under the sand, carries Sivir down to the Oasis of the Dawn, Ascends in a shaft of light in a buried chamber, and only then does the city come out of the ground.

He does not dream that he, Shurima's greatest emperor, can at long last earn his Ascension and bring back his broken city.

That last shot is the point. The ancient capital rises with the Sun Disc overhead and sheer walls on every side. If you built that region flat, you would be adapting the one Runeterra story that literally cannot happen on a flat map. Nasus has been walking those ruins the whole time.

The other number: 10,000 NPCs on routines

Hidden Mountain's density claim is the quieter benchmark. More than 10,000 interactive NPCs running daily schedules is what a modern open world is now expected to feel like when you log in. It's the same problem from the other end as Erenshor filling its raids with bots that recruit each other into guilds. One studio is populating the world so it feels lived in, the other is populating the group finder so it feels playable, and both are answering the question of what happens when a player logs in alone on a Tuesday.

What we actually know, which is very little

None of the above tells you what the Riot MMO contains. Riot has confirmed very little about the game beyond the basics: it's an MMO set in Runeterra, a playtest exists, and senior hires keep landing. Which regions are in it, how much of the world it covers, how big it is, when it takes place, what it runs on, and how it's paid for are all unrevealed. Anyone telling you otherwise is guessing.

That gap isn't going to close on its own either. Other studios are testing in daylight right now, which is the whole reason anyone can drop into EVE's new extraction shooter while Riot's MMO stays behind locked doors reads the way it does. Until Riot shows the game, the hires and the fiction are the only evidence on the table.

So the map below and the crests under it aren't a zone list or a starting area. They're the world Riot has spent more than fifteen years writing, and the raw material any Runeterra MMO would be drawing from. The geography in that fiction is stacked. Hidden Mountain is a live example of what it costs to honor that, and what you get back.
