About Blood
Blood is a first-person shooter that Monolith Productions developed on the Build engine. GT Interactive published it, with Eidos Interactive handling the European release. A shareware version came out for MS-DOS on March 7, 1997, and the full game followed on May 21 in North America and June 20 in Europe. Nick Newhard directed it, Matt Saettler produced it, and Daniel Bernstein and Guy Whitmore wrote the music. It has single-player and multiplayer modes.
A further release, One Unit Whole Blood, arrived in North America on July 15, 1998. Decades later Nightdive Studios remastered the game on its KEX Engine. Fresh Supply came out worldwide on May 9, 2019, and Refreshed Supply followed on December 4, 2025, with a Nintendo Switch 2 version on May 7, 2026. The remasters reached Windows, PlayStation 4 and 5, Xbox One, Xbox Series X/S and the Switch. Atari holds the rights today.
How it runs in your browser
DOS.Zone hosts the MS-DOS release, and Play sends you there in a new browser tab. js-dos, DOS.Zone’s open-source port of DOSBox to the web, emulates the kind of PC Blood was written for, so the original program runs inside your browser. DOS.Zone serves the game files, which means you don’t install anything or upload a copy of your own, and you can start without signing up. There are no ads on DOS.Zone.
The listing, titled BLOOD, has a rating of 5 from 652 player reviews and sits under DOS.Zone’s 3D action and first-person shooter tags. It doesn’t say whether you’re getting the shareware episode or the full registered game, so check the host’s page if that matters to you. Blood itself supports multiplayer, but DOS.Zone doesn’t list a multiplayer room for it, so treat this as a single-player game.
DOS.Zone has removed games before when rights holders asked, as it did with GTA 1 and 2 after a request from Take-Two, so a listing like this one isn’t guaranteed to stay.
Controls and devices
Blood is played with a keyboard and mouse. The host page doesn’t give the controls, so open the game’s setup or options screens to see which keys do what before you start.
Phones get virtual on-screen controls from DOS.Zone, but a shooter like this was designed around a keyboard and mouse, and a desktop or laptop is the more comfortable choice. Chromebook support hasn’t been confirmed.
Who it’s for
Blood is for fans of 1990s shooters who want to try one of the Build engine games without setting up an emulator. It shares that engine with Duke Nukem 3D and Redneck Rampage, and both of those also run on DOS.Zone, so you can move between them and compare what each studio did with the same technology.
Is Blood Free, Safe and Official?
Can I play Blood in my browser for free?
Yes. DOS.Zone runs the MS-DOS version free, with nothing to install and no account. It’s a single-player listing, as DOS.Zone has no multiplayer room for Blood.
Does Blood use the same engine as Duke Nukem 3D?
Yes. Monolith built Blood on the Build engine, which also powers Duke Nukem 3D and Redneck Rampage. In the browser, DOS.Zone runs the original DOS program in an emulated PC.
Does Blood work on a phone?
DOS.Zone provides virtual on-screen controls, but Blood was made for a keyboard and mouse, so you’ll be better off on a computer.
