What this browser project offers

The heading is Play Return to Castle Wolfenstein Multiplayer Online. The tagline names mp_beach and multiplayer in the browser. The hint says the real RTCW multiplayer engine, iortcw, compiled to WebAssembly.

A warning says the first load downloads about 380 MB of game data, cached after that, and recommends desktop Chrome. The meta description says no install. That download is the project's data, not a file you supply and not a launcher this site hosts.

Startup

Open https://rtcw.pieter.com, enter a player name up to 15 characters, and use Play. Plan for a large first load on a desktop Chrome session if you follow the page's own advice.

A script comment says phones and tablets use shared touch controls and that a desktop-only block is no longer applied. The visible warning still recommends desktop Chrome. This directory did not open the game page.
