Don't Starve Together Adds New Ocean Biome in Return of Them Update

Ocean Expansion Brings Cooperative Sailing to Don’t Starve Together

Klei Entertainment has unveiled the next major content expansion for Don’t Starve Together, introducing a comprehensive ocean biome that fundamentally changes how players explore and survive in the Constant. The Return of Them update, scheduled for release in Q3 2026, adds over 15 square kilometers of navigable ocean terrain, underwater exploration mechanics, and 12 new sea-dwelling creatures that challenge existing survival strategies.

The ocean biome represents the largest single content addition since Don’t Starve Together’s initial launch in 2016, according to Klei’s development roadmap published on Steam. Players will construct various watercraft ranging from simple log rafts requiring 8 logs and 6 rope, to advanced galleons that accommodate up to 6 players and feature storage compartments, cooking stations, and defensive cannons.

New Creatures and Environmental Challenges

The oceanic expansion introduces a diverse ecosystem of marine life that poses unique threats and opportunities for resourceful survivors. The Depth Dweller, a massive cephalopod creature, emerges during storm events and can destroy smaller vessels with its tentacle attacks that deal 75 damage per strike. Players must coordinate their movements and use harpoon weapons crafted from bone shards and silk to defend their boats.

Smaller creatures like Bioluminescent Jellies provide both danger and utility. These creatures inflict poison damage over 30 seconds when touched, but their harvested essence creates underwater breathing apparatus that extends diving time from the base 90 seconds to 4 minutes. The Coral Polyps, stationary creatures that grow on underwater rock formations, can be harvested for building materials but regenerate every 3-5 game days.

Cooperative Mechanics and Resource Management

The ocean content emphasizes collaborative gameplay through its boat construction and navigation systems. Larger vessels require multiple players to operate effectively, with designated roles for steering, sail management, and defensive positions. The Galleon-class ships feature a captain’s wheel that requires one player’s constant attention during navigation, while two additional crew members manage the rigging to optimize wind capture and speed.

Resource management becomes more complex with the introduction of saltwater purification systems and food preservation challenges. Fresh water sources are scarce on the ocean, requiring players to construct desalination equipment using 4 cut stone, 2 gold nuggets, and 1 purple gem. Food spoilage accelerates by 25% in the humid ocean environment, making ice boxes and preservation techniques essential for extended voyages.

Underwater Exploration and Diving Mechanics

Beneath the ocean surface lies a network of underwater caves, sunken ruins, and resource deposits that require careful planning to explore safely. The diving system introduces an oxygen meter that depletes at a rate of 1 point per second, giving players 90 seconds of base exploration time before drowning damage begins at 10 HP per second.

Advanced diving equipment extends exploration capabilities significantly. The Diving Bell, constructed from 6 boards, 4 rope, and 2 gears, creates a stationary air pocket that allows indefinite underwater stays within a 5-tile radius. The Pressure Suit, requiring rare deep-sea materials including 3 Kraken Ink and 2 Deep Pearls, provides 240 seconds of oxygen and protection from pressure damage in the deepest ocean trenches.

Underwater ruins contain unique crafting materials and ancient technology blueprints not available on land. The Tidal Generator blueprint, found in sunken temples, allows players to harness wave motion for electrical power generation, producing 75 watts during high tide cycles and 25 watts during low tide periods.

Weather Systems and Seasonal Changes

The ocean biome introduces dynamic weather patterns that affect gameplay beyond simple visual changes. Storm systems develop over 2-3 game days, beginning with increased wind speeds that boost sailing velocity by 40% but make steering more difficult. As storms intensify, wave heights increase, causing smaller boats to take structural damage at a rate of 5 HP per minute during peak conditions.

Seasonal variations alter ocean behavior significantly. During winter months, ice formations create navigational hazards but also provide fresh water sources when melted. Summer brings calm seas ideal for exploration but increases the spawn rate of aggressive creatures by 30%. Hurricane season, occurring every 20-25 days during autumn, generates massive storms that can destroy inadequately prepared vessels but also wash rare materials onto accessible beaches.

Integration with Existing Content

The ocean expansion seamlessly connects with Don’t Starve Together’s established land-based gameplay through coastal transition zones and resource trading opportunities. Players can establish port settlements that serve as staging areas for ocean expeditions, featuring specialized structures like the Shipwright’s Workshop for vessel construction and the Maritime Storage facility for organizing sea-specific resources.

Existing characters receive ocean-specific abilities that complement their land-based skills. Wurt, the fish-focused character, gains enhanced swimming speed and extended underwater breathing time. Wolfgang’s strength bonuses apply to rowing and sailing activities, while Wickerbottom can craft nautical charts that reveal ocean terrain and creature locations within a 20-tile radius.

The Return of Them ocean update represents Klei Entertainment’s commitment to expanding Don’t Starve Together’s cooperative survival experience through meaningful content additions that encourage teamwork and strategic planning. With its emphasis on collaborative mechanics, environmental challenges, and resource management complexity, the ocean biome provides veteran players with fresh survival challenges while maintaining the game’s core appeal of creative problem-solving in a hostile world.
