- Reported result
- The experimental browser port supports one map, core unit activities, a HUD/minimap and a basic opponent, but lacks major features and is not stable enough for general release.
- Human involvement
- The author assessed supported features and explicitly reported instability and substantial missing functionality.

How the agent did it
- Ported openage's existing simulation and related game systems to run in the browser.
- Adapted desktop OpenGL rendering to WebGL 2.
- Replaced native game-loop, UI, filesystem and audio paths with browser-compatible equivalents.
The author used substantial help from Codex to port SFTtech/openage, an open-source C++ reimplementation of Age of Empires II, to WebAssembly. They described the result as a narrow experimental browser port and said it was not stable enough for general release.
The existing simulation, pathfinding, production and combat code runs in the browser. Rendering was adapted from desktop OpenGL to WebGL 2. Codex replaced native game-loop, Qt interface, filesystem and audio paths with browser-compatible equivalents. The port reused converted graphics, interface, sound and music assets from the author's legally owned copy.
The reported prototype supports one deterministic map, unit control, resource gathering, construction and combat. It also includes a working HUD and minimap, plus a basic computer opponent using openage's command system. Missing features include campaigns, multiplayer, saves, replays, the full technology tree and some original rules. The author said the effort consumed almost their weekly Plus-plan limit, but did not provide an exact duration or cost.
