Tailored Solutions for Your Multiplayer Gaming Challenge

Whether you’re building a multiplayer masterpiece, hosting competitive tournaments, or collaborating with your development team, our products are designed to meet the unique needs of the gaming industry. Explore how our tools can power your success.

Seamless Communication Across Platforms

Crystal-Clear Voice Chat for Every Multiplayer Game

ODIN Voice provides seamless, full-volume voice communication for multiplayer games, supporting a wide range of platforms, including Unity, Unreal Engine, Apple, and Web. Its cross-platform capabilities enable unique use cases, such as allowing players in a web-based launcher or command interface to communicate directly with users in-game.

With easy integration, developers can get started quickly by downloading the ODIN package from the Unity Asset Store or Fab (Unreal). With minimal setup, your game will be ready to offer high-quality, low-latency in-game voice chat, creating a more connected multiplayer experience.

Immersion Through Realistic Audio

Dynamic Proximity Voice Chat for Advanced Gameplay Realism

ODIN Voice elevates gameplay with proximity-based 3D spatial audio, where voice volume dynamically adjusts based on player distance and environmental factors, such as walls or obstacles blocking sound. Combine this with 2D voice chat to enable simultaneous world chat and radio-based team communication, offering unparalleled realism and strategic depth. Advanced use cases include features like eavesdropping on enemy conversations, adding a layer of tactical gameplay that immerses players further.

Our SDKs natively integrate with Unity and Unreal Engine, leveraging their audio pipelines for easy setup and support of advanced effects like hall reverberations, distortions, and damping. For more sophisticated audio processing, ODIN includes built-in integration for Wwise and FMOD, empowering developers to create unique and immersive soundscapes tailored to their game.

ODIN is fully cross-platform, supporting PC, Mac, and consoles, ensuring seamless integration across all major gaming platforms.


“Selecting ODIN as the voice chat in our upcoming title, Gray Zone Warfare, was a pivotal decision driven by both technical and business considerations. Technically, ODIN ticks a lot of our criteria with its support for spatial audio, a ready-to-deploy Unreal Engine 5 plugin and the ability to meet any player load thanks to their cloud hosting. From a business perspective, the agility and openness of partnering with a company like 4Players meant we could work hand-in-hand to tailor the solution to our specific needs. This includes a seamless integration with Wwise, allowing us to modulate voice data for a more immersive and engaging player experience. Together, these factors made ODIN the undeniable choice for Gray Zone Warfare, enabling us to make our game even more memorable.”

Reliable Server Management

Scalable Server Hosting for Multiplayer Games

ODIN Fleet provides flexible hosting solutions tailored to your game’s unique needs. Whether you’re running long-lasting servers for persistent worlds in games like Minecraft or Ark, or dynamic servers for match-based sessions, ODIN Fleet scales effortlessly to handle both.

  • Persistent Game Worlds: Perfect for survival or sandbox games, these servers stay online continuously, with data persistence that allows players to join and leave at will.
  • Match-Based Sessions: Ideal for competitive or cooperative games, servers are spun up dynamically as players are matched or create private lobbies. Once the game ends, the server is stopped or recycled for the next session.

ODIN Fleet is designed with developers in mind:

  • Transparent Pricing: No hidden fees—our pay-as-you-go model ensures predictable costs.
  • Full-Service CI/CD Integration: Simplify server deployment and updates with seamless CI/CD pipelines.
  • Matchmaking Integration: Supports integration with Nakama, GameLift, or any other matchmaking solution via our easy-to-use APIs or CLI.

With global infrastructure, robust support for Unity, Unreal Engine, and other platforms, ODIN Fleet takes the complexity out of server hosting, letting you focus on delivering outstanding gameplay experiences.
