# Chain Tactics

What is Chain Tactics?

Chain Tactics is an open-source, fully on-chain 1v1 PvP strategy game that blends chess-like strategy with tactical RPG elements, played on a 9x9 grid. Players command unique units to destroy their opponent’s Fortress, leveraging Sovrun’s L2 infrastructure and the Sovrun SDK for transparency and community ownership.&#x20;

The SDK’s MUD Engine manages Chain Tactics’ on-chain game state, handling data for units, moves, and outcomes with efficient multi-threading, while the Game IDE Integrator bridges this logic to Unity, enabling developers to create rich visuals and custom frontends using familiar workflows \[Sovrun SDK].

Running entirely on-chain, the game eliminates centralized servers, ensuring transparency and immutability. Its modular, open-source design, powered by the headless client and Sovrun SDK, invites developers to innovate with custom frontends, AI agents, and gameplay extensions.
