The Doom series

id Software released Doom in December 1993, first as shareware and by mail order. You play a space marine fighting the forces of Hell through the moon bases of Mars, and its fast first-person action, network deathmatch and support for player-made levels shaped the shooters that followed. Doom II: Hell on Earth came out in 1994 and was the first Doom game sold in stores. Final Doom followed in 1996 with two new sets of levels for the Doom II engine, made by TeamTNT and the Casali brothers.

The series continued with Doom 64 (1997), Doom 3 (2004), Doom (2016), Doom Eternal (2020) and Doom: The Dark Ages (2025). id Software released the source code of the original engine in 1997, which is why so many source ports exist, including the ones that now run in a browser. id Software is part of ZeniMax Media, which Microsoft owns.

The browser versions listed here

  • Doom: the 1993 original in its MS-DOS version on DOS.Zone, which also runs a multiplayer room for it. A second host, silentspacemarine.com, offers a WebAssembly source port with online multiplayer, using the shareware episode.
  • Doom II: Hell on Earth in its MS-DOS version on DOS.Zone, with its own multiplayer room.
  • Final Doom: the 1996 follow-up in its MS-DOS version on DOS.Zone.
  • DOOM II Multiplayer: online Doom II deathmatch on the Odamex engine, compiled to WebAssembly by pieter.com. It plays on our page and puts you straight into the map that’s running.
  • Doom 3: the free Doom 3 demo from 2004, running on D3wasm, a WebAssembly port of the GPL id Tech 4 engine. It’s the demo, not the full game.

The DOS.Zone versions open dos.zone in a new tab, where its js-dos emulator runs the original game on an emulated PC. There’s nothing to install, no account and no ads.

Which one to try

For the single-player campaign, start with Doom on DOS.Zone and carry on with Doom II and Final Doom, all three as they shipped in the 1990s. If you want to fight other people, open DOOM II Multiplayer: it’s the quickest way into a match. All of them are played with a keyboard and mouse, so use a computer rather than a phone. For more first-person shooters, see Quake, Wolfenstein 3D and Duke Nukem 3D.

Playing Doom in a browser: questions

Is browser Doom official?

No. None of these versions is made or endorsed by id Software or Bethesda. They’re free projects run by DOS.Zone and by independent developers, and they could be taken down at the rights holder’s request.

Can I play Doom online with friends in a browser?

Yes. DOOM II Multiplayer drops you into a running deathmatch on Odamex, right on our page. The source port listed as a second host on our Doom page has online multiplayer, and DOS.Zone runs multiplayer rooms for Doom and Doom II.

Do I need the original Doom files?

No. Every version listed here loads the game data itself, so there’s nothing to install and no files of your own to supply.
