Doom

The original Doom in a minimal browser shell

The 1993 Doom casts you as a marine fighting a demonic invasion. Its appeal is immediate first-person combat: choosing weapons, reading the space around enemies and pushing through to the next area. This project approaches that original game as a compact runnable engine, rather than as the enhanced commercial Doom + Doom II package.

Why this Doom port is different

Jacob Enget designed doom.wasm around a small interface that other programs can use. The browser page is a deliberately simple demonstration of the same module also used by native and Python examples. It defaults to shareware data; its programming interface can load custom WAD data, but that is not the same as a polished drag-and-drop mod launcher.

Choose this version if you want to see a small WebAssembly implementation at work. For a longer campaign session, its missing audio is a substantial tradeoff: neither music nor sound effects are produced.

Use the classic keyboard layout

The example follows vanilla Doom controls. Arrows move and turn, Ctrl fires, Space operates doors and switches, and comma or period steps sideways. Learn the strafe keys early so that moving out of the way does not require turning away from a target.

A brief apparent freeze during a screen transition can be the original melting animation completing without intermediate browser frames. That documented limitation is separate from a failed game load. Retail content requires your own WAD data; the shareware default is not the complete paid game.
