# Command & Conquer: choose Chrono Divide, GeneralsX or OpenRA Canonical: https://playable.wtf/guides/command-and-conquer-versions/ Written: 2026-10-17 Start with the game you want: Red Alert 2, Generals Zero Hour and OpenRA’s earlier Westwood games have different armies, rules and setup. ## Choose the game first Choose the battlefield before choosing the engine. [Chrono Divide](https://playable.wtf/games/red-alert-2-browser/) recreates vanilla **Red Alert 2** for browser play. [GeneralsX Web](https://playable.wtf/games/generals-zero-hour-browser/) runs **Generals: Zero Hour** using your installation. [OpenRA](https://playable.wtf/games/openra-openra/) is an installed collection with its own interpretations of earlier Westwood games. Three routes with different games and requirements | Project | Choose it for | Prepare first | | --- | --- | --- | | [Chrono Divide](https://playable.wtf/games/red-alert-2-browser/) | Red Alert 2 multiplayer in a browser (A beta aiming for vanilla-engine feature parity.) | A supported browser; complete the client's game-data setup. | | [GeneralsX Web](https://playable.wtf/games/generals-zero-hour-browser/) | The later 3D Zero Hour game (The creator describes complete-game scope.) | Your installed Zero Hour copy and a WebGPU browser. | | [OpenRA](https://playable.wtf/games/openra-openra/) | Revised Tiberian Dawn, Red Alert or Dune 2000 rules (OpenRA's Red Alert is the first game, not Red Alert 2.) | A Windows, macOS or Linux release and its first-run asset setup. | All three ask you to manage an economy while commanding units. The choice changes the armies and rules you learn, not merely the way the same executable launches. Agree on the project with friends before installing anything. ## Start Red Alert 2 in Chrono Divide Use [Play Beta on Chrono Divide's site](https://chronodivide.com/), complete the client setup, and choose classic left-click or modern right-click commands before a match. The creator documents multiplayer, original maps and replays. Its vanilla Red Alert 2 goal does not make this a complete Yuri's Revenge package. For a local import, use your original Red Alert 2 installation's MIX files. The [project's storage guide](https://github.com/chronodivide/mod-sdk#file-and-folder-structure) identifies `ra2.mix`, `multi.mix` and `language.mix`; Zero Hour's BIG archives are a different format. The client supports drag-and-drop and archives with a single nested directory. Keep file import separate from account setup. The [client notes](https://chronodivide.com/patch-notes.html) describe a global account with regional nicknames; an existing nickname can be linked from the nickname screen. In Quick Match, use **Invite Player…** for a party. Replays let you revisit a match; they are not a save from which to resume commanding. If an import fails silently or Quick Match stays unavailable after visiting the ladder, the 0.84.1 notes specifically address those problems. Reload to pick up the current client before repeating the same failed step. ## Bring Zero Hour to GeneralsX Choose GeneralsX Web when you specifically want Zero Hour's USA, China and GLA armies. The [creator's requirements](https://github.com/origami-ltd/wasm-generals#requirements-to-play) call for your installed Steam, EA app or disc copy. An unopened installer, a Red Alert 2 folder or a renamed archive is not that installation. 1. Open [generals.wasm.ltd](https://generals.wasm.ltd/) over HTTPS in a WebGPU-capable Chrome or Edge browser. 2. Point the launcher at your installed Zero Hour directory. The engine reads its `.big` archives from your disk as needed. 3. Enter the game's own menus; **Esc** opens its original pause menu. The project targets the complete game and distributes no game assets. Its documented multiplayer uses a WebSocket relay and a shared link for players on your network. Arrange that LAN setup explicitly; Chrono Divide invitations and OpenRA servers belong to other games. ## Install an OpenRA mod OpenRA is the choice for a modern interpretation of earlier RTS games: production queues, attack-move, stances, fog of war and ongoing balance changes. Its [three official mods](https://www.openra.net/about/) are Tiberian Dawn, Red Alert and Dune 2000. Tiberian Sun remains a separate development effort. 1. Choose **Release** on the [OpenRA download page](https://www.openra.net/download/) for ordinary online play. Playtest is a separate preview channel. 2. Install the package for your computer and open the desired mod. On Linux, the official AppImages are supplied per mod. 3. Let that mod download its original assets or copy them from your discs when prompted. Then choose the left-click or right-click control scheme you prefer. For friends who cannot join one another, compare both the mod and release channel. A Red Alert match and a Tiberian Dawn match use different rules even inside OpenRA. Replays and observers help you study those rules after a match. ## Match the device to the session Chrono Divide advertises phone and tablet access, but also gives a minimum display size of **1024×768**, 4 GB RAM and a 64-bit browser. That is a reason to prefer a roomy screen for its battlefield and sidebar. Its own performance advice favors the other listed browsers over Firefox. Plan GeneralsX around a desktop with access to your installed files and WebGPU. OpenRA's supported downloads are desktop applications. If your only device is a phone, these two routes do not provide the same documented mobile starting point as Chrono Divide. Keep saves, replays and accounts with the project that created them. For a different kind of strategy session, the [OpenTTD comparison](https://playable.wtf/guides/openttd-browser-native/) explains a browser route with explicit save-file transfers to a native application. ## Project reading - [Chrono Divide · features and device requirements](https://chronodivide.com/) - [Chrono Divide · imports, accounts and client updates](https://chronodivide.com/patch-notes.html) - [GeneralsX Web · Zero Hour requirements and scope](https://github.com/origami-ltd/wasm-generals#readme) - [OpenRA · games and revised rules](https://www.openra.net/about/) - [OpenRA · releases and first-run assets](https://www.openra.net/download/) - [Chrono Divide · original MIX assets and browser storage](https://github.com/chronodivide/mod-sdk#file-and-folder-structure)
