About Half-Life: Deathmatch

Half-Life is the 1998 first-person shooter that was Valve’s first product and the start of the Half-Life series. Sierra Studios published it for Windows. Its campaign follows Gordon Freeman, a theoretical physicist escaping the Black Mesa Research Facility after a disastrous experiment lets aliens overrun it, and mixes combat with exploration and puzzles. Kelly Bailey composed the music, and the game ran on Valve’s GoldSrc engine.

Alongside that single-player story, Half-Life shipped with a multiplayer mode, and deathmatch is the part this page is about: instead of working through Black Mesa, players fight each other in arenas using the game’s weapons. The original came out on Windows. Valve later published Mac and Linux versions, and Gearbox Software ported the game to the PlayStation 2. Valve publishes the Windows version today and holds the rights to the series.

How it runs in your browser

This isn’t emulation. The DOS.Zone team built a browser port of Half-Life’s multiplayer, so no old PC is being simulated in your tab. DOS.Zone doesn’t say which engine powers the port.

According to DOS.Zone, the port keeps the original game’s deathmatch, with the familiar arenas and weapons and up to 32 players per match. Press Play and dos.zone/hldm opens in a new tab. You don’t install anything or bring your own copy of Half-Life, there’s no account to create, and DOS.Zone shows no ads. The page lists an average of 4.8 from 12,175 player reviews.

Every match is online against other people. We haven’t tested how well online games run, so give it a try before you plan a session with friends around it.

The story campaign isn’t included. On DOS.Zone’s forum in September 2026, its developer said porting the full single-player Half-Life would cost too much for them. If you want Gordon Freeman’s story instead, Half-Life runs in a browser through a separate Xash3D port.

Controls and devices

Half-Life: Deathmatch is played with a keyboard and mouse. DOS.Zone doesn’t publish the key bindings, so look through the game’s controls or options menu after it loads, before you join the fight.

DOS.Zone offers virtual on-screen controls for phones, but a shooter built around aiming with a mouse is a poor match for a touchscreen, and a desktop or laptop is the better fit. Chromebooks haven’t been checked.

Who it’s for

It suits players who spent time in Half-Life deathmatch servers years ago and want a quick round without installing anything, and shooter fans curious about how the game plays against other people. For more deathmatch in a browser, DOOM II Multiplayer drops you into a running Odamex match, and Valve’s Counter-Strike 1.6 has live public servers in a browser tab.
