List of attempted Blood source port and recreation projects.


Attempted Source Ports[edit]

The source code to Blood was never released; however, source ports have been attempted using released Build engine, Duke Nukem 3D, Shadow Warrior, or the leaked Blood Alpha code, as well as original programming using reverse engineering. Based on original or already free software source code and only reading the original game's assets, these projects are considered more clear legally speaking. They should also be able to run custom content such as Bloody Pulp Fiction or Death Wish. The exact definition of what is a source port is debatable however, in regards to lacking the official source code, and methods of reverse engineering will vary.


  • BloodGDX - a project to port Blood using the libGDX framework for Java. Single and multi-player.



"The XL Engine is an engine that runs the 'XL Games', which are enhanced remakes/ports* of the classic games. Essentially they are remakes in the spirit of a port, or to put it another way, they emulate the original games and then provide optional enhanced features on top in order to improve playability and visuals. All these games will be able to use the 'Pure Renderer', which is a software renderer that can support the original 8 bit rendering and resolutions. Basically this means that you can play the games as they original looked and played or play in higher resolutions and color depths with a variety of enhancements. You choose how close to the original you want the games to be."

The XL Engine, a reversed engineered port of the Jedi Engine used in Star Wars: Dark Forces and Outlaws, is attempting Blood support since first announced on December 22, 2010. Pursuant to this, support for the original Shadow Warrior has also been prototyped.


"This is a modified version of DosBox v0.74 called BloodBox, that will serve as the platform for a reverse engineering effort of the classic first person shooter Blood. Specifically version 1.21 (The GOG version should work) After loading the main executable of the game, BloodBox injects calls to a special interrupt at the start of certain functions. These functions were then reverse engineered and implemented in BloodBox itself. In this way, instead of having to reverse engineer the entire game, only code useful for speeding up, bug fixing, modding and adding features will have to be considered."

Blood 32[edit]

The first ambitious port, started in 2005 and last updated in 2009 by Justin "icecoldduke" Marshall and also known as WinBlood. It first attempted to port the game assets to the Build engine port hosted on before later being restarted from scratch based on JFDuke3D, releasing a few screamshots and four public alphas.


Registered by Jacob Moorman on April 12, 2010 and last updated on April 11, 2013, OpenBlud attempted to create a basis with the original Shadow Warrior source code while also porting to 32-bit Windows systems.

Build Sharp[edit]

"BuildSharp is an application, currently in development, that can read from and utilise assets from Build games and be used to generate games via a scripting language. Developed in C# and using XNA (but planning to move to MonoGame when able) The primary focus is on the Build game Blood as it is currently one of the main three Build games (the others being Duke Nukem 3D and Shadow Warrior) that has not had it's source code released. This site is still quite new, so please check out our Facebook page for details of our development so far."

A project aiming to reverse engineer Blood onto the .NET Framework; first announced May 22, 2014 and last updated on June 13, 2015. Announced on Facebook as in "hibernation" as of August 14, 2017.

Blood EX[edit]

"EX moves away from BUILD in terms of mechanics and basically reproduces the original game in a modernized engine, which means floating point math instead of fixed point and timing/speed/movement etc has to be scaled down to match the original game, so theres bound to be some minor flaws here and there. Though despite of that, EX will have a more dedicated focus on modding and customization... The way I handle it is anything regarding to damage values, health, etc is reverse engineered, because that's the most important things that needs to be done right. Anything regarding to player weapon swaying and object momentum speeds (such as how far you throw dynamite, or how much an explosion knocks you back) is entirely empirical, though I do rely on the assembly as a guide. AI behavior is 100% identical and taken directly from the disassembly. Though I do add a bit more to it so it can be easily customized by modders. The only thing I am concerned about is how the enemy aims at the player. Build engine games uses a fixed-point slope value while Kex uses atan2/angle pitch to determine the aim.... which results in the AI being a tad more accurate even while the player crouching. I have some ideas to emulate the fixed point slope behavior though. Everything else (renderer, collision, resource management, etc) is done from scratch."

A project "under tight wraps" started sometime after May 2015 by Samuel "Kaiser" Villarreal based on his prior KEX engine ports. Superseded now that it has been announced that Kaiser is working on an official remaster of the game for Night Dive Studios using this work as a base.

Attempted Recreations[edit]

Most of these take the form of total conversions for other games, sometimes with attempts to imitate the Blood game logic as well as its aesthetics. Others are better classified as original fangames. As with all fan made projects using copyrighted assets, there are questions as to their legality; Transfusion received a quitclaim license however.



Blood Evolution[edit]

A project to replicate Blood atop of Unreal Engine 4 by D!rt, an Irish 3D artist who worked on the 2013 remake of Rise of the Triad and the earlier Blood Source project. The first news post is from January 7, 2015. Once seemingly being merged into the Blood Fan Remake on Unity 3D, a video of the current state of the project was released on March 15, 2018.

Blood Fan Remake[edit]

A project to recreate Blood atop of the Unity 3D engine first announced on April 23, 2017 by OrdinaryFpsFan789. Currently hoping to complete a full remake of E1M1: Cradle to Grave. A demo was released on May 22, 2017. D!rt, formerly of both Blood Evolution and Blood Source, is now listed as a modeller.


Bloodmod To Duke[edit]

An early attempt at doing a Blood total conversion for Duke Nukem 3D, announced on August 17, 2005 by TheChosenOne.

Cradle to Grave[edit]

Similar to the later finished BloodCM, Cradle to Grave (or C2G) was another project to add Blood enemies, objects, and styles to EDuke32. It was worked on by Daedalus, Dimebog, Daedolon and others from The Postmortem going under the title of Bunch of Butchers. First announced on June 23, 2008, it received its last news post on March 23, 2011 and has remained dormant.

Blood Source[edit]

A project to port Blood to Valve Corporation's Source Engine by The Chosen; superseded by Blood Evolution. The first news post was released on February 24, 2009 and the last on May 27, 2012.


An attempt to succeed Transfusion using the X-Real engine derived from id Tech 3.

Dead Reckoning[edit]

A project by Justin "icecoldduke" Marshall, creator of WinBlood, attempted to port Blood assets onto id Tech 3, announced on June 2, 2009.
