Into The Depths Multiplayer Guide: Co-op & Modes

Is Into The Depths a Multiplayer Game?

As of its official release on June 10, 2026, Into The Depths is strictly a single-player experience. Developed and published by SmelJey, the game focuses on a solitary journey into the unknown depths. There are no cooperative or competitive multiplayer modes available at launch. The core gameplay loop—building a colony, managing resources, and exploring procedurally generated caverns—is designed around a single commander making all critical decisions.

This may come as a surprise to some strategy fans, but the game's Roguelite elements and deep simulation mechanics are tailored for a personal, uninterrupted campaign. You will not find a "multiplayer" button in the main menu. Instead, the challenge comes from mastering the environment and your own strategic choices.

Why No Multiplayer at Launch?

The developer, SmelJey, has prioritized a polished and deep single-player foundation. Introducing multiplayer would require significant changes to the game's core systems, including real-time pause, resource sharing, and the Roguelite progression loop. The current game is built around a single-player narrative of exploration and survival.

However, this does not mean the community is without options. The game's modding community is expected to be active, and players may create custom scenarios or tools that simulate cooperative play. For official information, always check the official Steam page. If you are looking for a game to play with friends, you might want to explore other titles, but for a deep solo strategy experience, Into The Depths is unmatched.

Future Multiplayer Possibilities

While no official plans have been announced, the success of the game could lead to future updates. SmelJey has not ruled out the possibility of a co-op mode in a post-launch update or DLC. Many colony sims and strategy games have added multiplayer features years after their initial release.

If a multiplayer mode were to be added, it would likely take one of two forms:

• Cooperative Mode: Two players managing the same colony, one focusing on exploration and combat, the other on base building and resource management.
• Competitive Mode: Players racing to colonize the deepest caverns or competing for limited resources on the same map.

For now, players should enjoy the rich single-player content. You can learn more about the game's core mechanics in our Mechanics Guide.

What About Local Co-op or Split-Screen?

There is no local co-op or split-screen support. The game is designed for a single player using a mouse and keyboard or controller. The interface and UI are optimized for one person managing the entire colony. Attempting to share control would be cumbersome due to the real-time nature of the game and the need for precise micro-management.

If you are looking to share the experience, consider taking turns on a single save file, or streaming your gameplay to a friend. This allows for shared decision-making without the technical challenges of a true multiplayer implementation. For more tips on surviving the depths, see our Beginner Tips.

Community and Shared Experiences

Just because there is no in-game multiplayer does not mean you are alone. The Into The Depths community is active on forums and social media. Players share their colony layouts, discuss strategies for difficult bosses, and trade tips for resource management.

You can participate in the community by:

• Sharing your most successful colony layouts.
• Discussing strategies for the Boss Guide.
• Comparing your progression with others in the Progression Guide.

The single-player focus allows for a deeply personal and challenging experience, which is the core of what SmelJey intended. Embrace the solitude and conquer the depths on your own terms.

Final Verdict on Multiplayer

Into The Depths is a single-player game. It does not feature any form of multiplayer at launch. This is a deliberate design choice that focuses the game on a rich, personal strategic experience. While future updates may change this, players should purchase the game expecting a solo adventure.
