Metaplay SDK Release 38 – Metaplay Agent and browser-native clients

Metaplay SDK Release 38 shipped on August 26, 2026. The largest addition is the Metaplay Agent, which teaches coding agents how the Metaplay SDK works. The release also previews browser-native game clients, adds in-game currency offers, and upgrades two core LiveOps Dashboard views.

Metaplay Agent: SDK skills for coding agents

The Metaplay Agent teaches Claude Code, Codex, OpenCode, and other coding harnesses how the Metaplay SDK actually works. With the skills installed, an agent can build new game features faster, catch SDK usage mistakes in your code, and diagnose everything from player incidents to server errors.

Getting started takes one prompt:

Run `metaplay skills try` to discover available skills, then review all the PlayerActions in my code.

Run metaplay skills install, commit the result, and the whole team gets the skills in every session. See the Metaplay Agent guide for how to use it effectively.

Browser-native game clients (preview)

Metaplay now supports game clients that run entirely in the browser: C# with Blazor WebAssembly instead of Unity, running against a normal Metaplay game server with the usual shared game logic. It is aimed at fast, AI-driven prototyping – a browser client is all code and no editor, so coding agents can generate the client and the backend in one C# codebase, iterate in seconds, and test the result by driving the running game in a real browser.

The HelloBlazorWasm sample shows a full working project.

In-game currency offers

Offers with an in-game currency cost, instead of real-money in-app purchases (IAP), are now supported out of the box and need less custom work. See the in-game currency offers cookbook.

LiveOps Dashboard: faster lists and localization debugging

The Localization Contents view has been rewritten to handle larger datasets with locale-aware search. A new list card component rolls out across the dashboard: faster rendering, more data, presets for frequently used filters, and richer filtering, sorting, and highlighting.
