Free Unity SDK with Helpful Tools and Features
Our Unity SDK aims to save you time and make development easier. It includes features like text and voice chat, matchmaking, network LOD, multi-client simulation, lag compensation, and Netcode Rollback, all ready to use. Plus, we regularly add new tools and features to keep you up-to-date.
Add Multiplayer Without Network Coding
With Alteruna, Unity creators can easily add multiplayer to their games without needing programming skills. Just drag and drop to sync changes, stats, voice, and more in the editor. Set everything up to meet your needs and concentrate on developing your game's main features while we manage the networking.
Adaptable Structure for Your Game Requirements
Alteruna Multiplayer provides a flexible hosting and server system for your game. With Our cloud server, the main room controls the game's status while clients manage their own objects. The Dedicated Game Server, where a game instance runs on the server, is ideal for competitive games. We also allow Peer-to-Peer connections over LAN, enabling any client to function as both client and server. This adaptability guarantees smooth multiplayer experiences suited to your game's specific needs.
Superior Speed for Seamless Playing
Alteruna’s efficient transport protocols, using both UDP and TCP, ensure fast data transfer between clients. By reducing data traffic, we improve your game’s performance, making multiplayer experiences smoother, more responsive, with less lag and quicker interactions.
Easy Cross-Platform Support for Any Game
Developing for different platforms is easy with the Alteruna Unity SDK. Just select your platform in the editor and build your game for mobile, PC, web, consoles, or XR. Alteruna Multiplayer supports all these options, so your game can reach players everywhere.
