Play Command & Conquer in Your Browser

The Command & Conquer series

Westwood Studios released Command & Conquer in 1995, with the Global Defense Initiative fighting Kane’s Brotherhood of Nod. It made real-time strategy a mainstream genre, with full-motion video briefings between missions. Red Alert followed in 1996 as an alternate-history prequel, with the Allies fighting the Soviet Union for Europe, and Red Alert 2 arrived in 2000.

Electronic Arts bought Westwood in 1998. Its EA Los Angeles studio made Command & Conquer: Generals and its expansion Zero Hour in 2003, set in a modern war rather than the earlier games’ worlds. The series continued with Command & Conquer 3, Red Alert 3 and Command & Conquer 4, and a Remastered Collection of the first two games came out in 2020.

The browser versions listed here

• Command & Conquer: the 1995 original in its MS-DOS version on DOS.Zone. EA made it freeware in 2007.
• Command & Conquer: Red Alert: the 1996 prequel in its MS-DOS version on DOS.Zone, freeware from EA since 2008.
• Command & Conquer: Red Alert 2: remade for the browser by the fan project Chrono Divide, with skirmish and ranked online play. It needs files from your own copy.
• Command & Conquer: Generals Zero Hour: a WebAssembly port on DOS.Zone, built from the source code EA released in 2025.

The DOS.Zone versions open in a new tab, with nothing to install and no account. Chrono Divide also opens on its own site.

Which one to try

Start with the original Command & Conquer or Red Alert: both are freeware, so they’re the safest picks and the quickest to start. Red Alert 2 is the one to choose for online matches, if you still have the game files. Generals Zero Hour suits players who want the later, faster style of the series. All four are played with a keyboard and mouse. For more strategy games, see Dune II, the Westwood game that came before Command & Conquer, and Warcraft II.
