Get the Wolfenstein 3D shareware (free, legal)
The shareware episode (data files) + a Win32 source port
You need two pieces, both free and legal:
- The shareware data — the freely-redistributable first episode (the
*.WL1files:VSWAP.WL1,MAPHEAD.WL1,GAMEMAPS.WL1,VGAGRAPH.WL1,VGAHEAD.WL1,AUDIOT.WL1,AUDIOHED.WL1). Apogee released episode one as shareware to be copied at no charge; the Internet Archive keeps preserved copies. - A Win32 source port — a modern, open-source rebuild of the engine that runs natively as a Windows EXE. ECWolf (grab the 32-bit Windows build) or the leaner Wolf4SDL.

Put the source-port EXE and all the *.WL1 files in one folder to play it on your desktop — you need none of that here, since this page already boots the shareware episode. © id Software / Apogee. Only the shareware episode is free to redistribute. The registered episodes, the Nocturnal Missions, and Spear of Destiny are commercial — buy those from id / Steam.
How it works & what to expect
This page runs the original 16-bit DOS Wolfenstein 3D — the actual 1992 WOLF3D.EXE — inside DOSBox compiled to WebAssembly. Nothing is emulated twice and nothing is rebuilt: it's the shareware episode exactly as it shipped, booting in a couple of seconds.
You get the genuine game: B.J. Blazkowicz, the maze-like bunkers, secret-wall pushing, and that unmistakable raycast look. Sound is the original AdLib/PC-speaker output, so it sounds the way it did in 1992 rather than the way a modern port would render it. Wolfenstein 3D is featherweight by today's standards, so it runs at full speed on any current machine — older Chromebooks and tablets are the only place you might notice it struggle.
Source ports, if you want one on your desktop
id open-sourced the Wolfenstein 3D engine in 1995, and the community built modern rebuilds — ECWolf and Wolf4SDL — that read the very same shareware .WL1 data with higher resolutions, mouse look and modern displays. They're worth having on a desktop.
They're desktop programs, though. This page deliberately runs the original DOS build instead, because that's the version that needs no setup from you at all.
Frequently asked questions
Can I play Wolfenstein 3D online for free with no download?
Yes. Apogee and id released episode one as shareware in 1992 to be copied at no charge, and it's been freely distributed ever since. This page runs that shareware episode in your browser — nothing to download, nothing to install, no account.
Can I play Wolfenstein 3D unblocked at school or work?
In most cases. The shareware episode is a 655 KB download and it runs inside the browser tab under DOSBox compiled to WebAssembly — no installer, no admin rights, nothing written to the machine. That is why it works on locked-down laptops where a downloaded game would not. If the network filter blocks this domain outright, though, nothing on the page can get around that.
Is the Wolfenstein 3D shareware legal to play here?
Yes, for the shareware first episode. The registered episodes, the Nocturnal Missions and Spear of Destiny are commercial and are not included — buy those from id or Steam.
Is this the real Wolfenstein 3D or a remake?
The real thing: the original 1992 DOS executable and its original data, running unmodified inside DOSBox. It isn't a fan re-creation and it isn't a source port — it's the game as it shipped.
What are the controls?
Click the game screen to capture your keyboard. Arrow keys or WASD move, Ctrl fires, Space opens doors and pushes secret walls, the number keys 1–4 switch weapons, and Esc opens the menu.
Why might it run slowly?
An x86 CPU is emulated inside WebAssembly, so you get roughly 10–40% of native speed. Wolfenstein 3D is light enough that this is plenty on any modern laptop; very old tablets and Chromebooks may feel sluggish.
Does it save my progress?
Yes, and not only from the game's own save menu. Close the tab mid-level and the next visit offers to put you back exactly where you were, because the whole emulator state is snapshotted to your browser's storage. Nothing is uploaded and there is no account — the save lives on the device you played on, which also means it does not follow you to another computer.
