GeneralsX Web runs Command & Conquer: Generals – Zero Hour, EA Los Angeles's 2003 expansion to the real-time strategy game Generals, in the browser. Erasmo "ebellumat" Bellumat made the WebAssembly port as part of wasm.ltd, a preservation initiative by Origami. It compiles GeneralsX, fbraz3's cross-platform engine based on EA's source code release, with Emscripten and draws through WebGPU via a Direct3D 8 translation layer. The README calls it the complete game with no features cut. You supply the game data: the page reads the .big archives of your own installed copy from your disk.

How to play

Wait for the runtime to download, then click Play.
Click Select folder or file and choose your Zero Hour install folder; the help text says you will then be asked for the base Generals folder. A folder holding a .zip, .iso or .bin/.cue you never unpacked also works; the page extracts it in place.
In the header, pick Display 16:9 or 4:3 and Boot Fast start (skips the intro movies and menu map) or Full start.
Play with keyboard and mouse. Esc opens the game's own pause menu.

What you need

Browser: a desktop browser with WebGPU; the site names Chrome and Edge. The engine reserves about 2 GB of memory at start, which the site says iPhones and iPads do not allow.
Input: keyboard and mouse. The site says there are no touch controls.
Files: an installed copy of Zero Hour and the base game (Steam, EA app or disc). RAR archives and uninstalled disc files (.cab) are not accepted.

Good to know

The site says the files never leave your machine. It remembers your folder between visits; Reset forgets it.
LAN multiplayer runs over a WebSocket relay that the local server in the source repository provides, with a link to share with players on your network.
EA released the source code of Generals and Zero Hour under GPL-3.0 on February 27, 2025.
The repository was created on August 5, 2026. The port first ran at generals.wasm.com.br and moved to generals.wasm.ltd on August 12, 2026; the old address redirects.
