If you want to know when Ocean Odyssey returns, how the original mode worked, and what made it stand out, this guide covers the key details. You can also find more PUBG MOBILE updates and guides on TOPUPlive.

▍What Is Ocean Odyssey?

Ocean Odyssey is an underwater-themed gameplay experience introduced in PUBG MOBILE Version 3.3. It transformed parts of Erangel into an underwater setting, adding submerged locations, special items, and unique encounters to the classic battle royale map.

At the center of the original experience were the Ocean Palace, Trident, and giant Kraken. These elements worked together to create a themed gameplay experience built around underwater exploration, special rewards, and encounters that were different from a standard Erangel match.

Classic Ocean Odyssey Elements

The following elements were part of the original Ocean Odyssey experience. PUBG MOBILE has not confirmed that every original feature will return in exactly the same form in 2026, so these should be viewed as a look back at the classic mode rather than a complete list of confirmed 2026 mechanics.

▍Ocean Odyssey Return Details

Ocean Odyssey will return to PUBG MOBILE on September 30, 2026, as part of Version 4.6. The themed mode will be available on Ranked Erangel for a limited time.

According to the Version 4.6 update information, Ocean Odyssey is scheduled to remain available through November 11, 2026, at 5:59 AM.

The Version 4.6 update also brings a new mystery to Erangel. A giant serpent can break through the ground, while weakened sections of its stone shell contain scales and supply rewards for players who manage to break through them.

▍Ocean Palace Encounter Details

The Ocean Palace was one of the main special locations in the original Ocean Odyssey. Players could dive underwater to reach the palace, where special crates and themed supplies were available. The area was surrounded by a special water membrane that allowed players to move normally inside the palace, while players within the area could also revive after being eliminated.

The main objective was the Trident in the center of the palace. Once its seal was released, a player could pull it out to obtain the Trident, while additional supplies and a Poseidon Respawn Card appeared at the same time.

But taking the Trident also triggered the palace's next phase. After the special sequence, the Ocean Palace began to flood, forcing players to leave the area before they ran out of air. This made the encounter a clear risk-versus-reward sequence: enter for better loot, secure the Trident, then escape before the palace floods.

▍Other Features in Ocean Odyssey

The mode also introduced several themed locations and items, giving players additional ways to find supplies, move around the map, and escape dangerous situations.

The following features were part of the original 2024 Ocean Odyssey experience and are shown here as a reference for how the mode previously worked.

Forsaken Ruins contained hidden switches that could open the entrance to an underwater Sea Treasury. Players could solve the mechanism inside to gain access to additional themed rewards.

Water Prisms were another special feature scattered around the map. Players could break the barrier surrounding a Water Prism and access the supply crate inside.

The mode also introduced special mobility and survival items. The Whale Escape Pod could carry an entire team toward the Playzone, while the Poseidon Respawn Card allowed players to return to the battleground after being eliminated.
