Caleb was once a feared gunslinger, until he met a woman who was involved with a mysterious cult known as Cabal. Caleb, too, is sucked in, and soon becomes one of the Chosen - the most favored worshippers of the evil god Tchernobog. But one day, Tchernobog inexplicably kills the four Chosen, including Caleb. Mysteriously resurrected years later, Caleb is out to get revenge, and learn why his lord cast him down so abruptly.

Blood is a first-person shooter with horror elements, which uses the Build engine. Similarly to Duke Nukem 3D, the environment is interactive: many objects can be physically moved or affected in other ways. Destruction of landscapes is possible (although only in specific spots), with bullet holes being left by misplaced shots. The Build engine version is 2.5D, so there are rooms above rooms and puzzles which are based on this.

The game consists of four episodes, each containing a set of maps that have to be traversed by the protagonist in a specific order. The levels are usually realistic-looking structures, e.g. a carnival complete with twisted attractions, a city district, a moving train, etc.

Throughout the levels, Caleb will have to find keys (up to six in a level) and hit switches in order to work his way to the exit. On the way, he will meet a variety of enemies, such as zombies that tend to come back to life after killed, cultists armed with shotguns and tommy guns that shout in pseudo-Latin language, crawling hands that attempt to choke him, hell-hounds that can set him on fire with their breath, and many more. Boss battles await Caleb at the end of each episode.

To defend himself against this menace, Caleb utilizes a variety of weapons: a pitchfork; a flare gun that can set enemies on fire; a sawed-off shotgun; a tommy gun; a napalm launcher; TNT bundles which come in three different varieties; a home-made flamethrower made of an aerosol can; a tesla cannon that electrocutes enemies; a magical staff dubbed "Life Leech"; and a voodoo doll.

There are items to pick up strewn around. Unlike most other 3D shooters, the protagonist's health is not replenished via medikits, but by "Life Essences", heart-like power-ups randomly dropped by enemies upon their death. It is also possible to find armor, which comes in three different varieties - Physical, Fire, and Spiritual, each one defending Caleb from different attacks. There are also other power-ups: some (such as Jumping Shoes or Doctor's Bag) can be picked up and activated at any time, while others (such as Partial Invisibility) activate immediately when taken.

As the title implies, violent and gory imagery plays a significant role in the game. Enemies might explode when taken out; it is possible to kick severed heads; impaled victims can be found lying around; enemies die in different ways depending on how they are attacked and in which part of their body, etc.

3dfx patch

Monolith released an alpha patch for Blood that provided 3DFX support. Unfortunately, being an alpha patch, it only works with version 1.0 of Blood, not One Unit Whole Blood. It is also incompatible with Voodoo Rush and Voodoo 2 chipsets.


The strange language spoken by the cultists is supposed to be a combination of Latin and Sanskrit. Sanskrit is the ancient language of India, from which several modern languages of that region originated.

Cut features

One early feature that Q Studios was planning to add to Blood was the idea of "BloodLust". According to this feature, each time when the player killed a minion of the Dark God, his BloodLust meter climbed a notch. If his BloodLust climbed high enough, he metamorphosed into the Beast. As the Beast, he was supposed to be stronger and faster than a human, but he was also limited in his choice of weaponry. Of course, BloodLust waned with time--if the player did not kill frequently, he reverted to human form. This feature was not added to the final release of the game.

Death Mask

Death Mask, the power-up that makes you invincible for a short period of time, does not tint your view with color while active, so it's impossible to see when it runs out, which makes it somewhat less useful. The Monolith team admitted that they forgot to implement this.


Apogee were the ones who started production on this game in 1994. The developers were Q Studios Corporation (an independent game development studio). In the short while they were working on it, they called it Horror 3D. After a while the rights for the game was sold to Monolith which completed the game and changed the name to Blood, which we're familiar with today.


Some versions of Blood came with a second CD that contained demos and the video for Love you to Death by the appropriately gloomy band Type O Negative.

German index

On June 28, 1997, Blood was put on the infamous German index by the BPjS. The game group contains more information about what this means.


When you stand still for a few seconds, Caleb starts to sing lounge classics. Some of the songs he knows are My Way, Puttin' on the Ritz, Somewhere Over the Rainbow. There's No Business Like Show Business and Strangers in the Night.


  • The game contains easter eggs with references to Jack Nicholson, Duke Nukem and The Crow. The tips & tricks section contains information how to reach them.
  • In the level after the train level, you will able to see in the rest of the train, the clothes of Harrison Ford's charachter in The Fugitive
  • The cheat code for god mode in Blood is 'mpkfa', where 'mp' stands for Monolith productions and 'kfa' is taken from 'idkfa', the cheat code for all weapons in DOOM. It seems like Monolith was paying a tribute to DOOM.
  • In the first level of the third episode, there's a secret room which is based on the infamous "Sloth" murder from the movie Se7en. There are those goody-smelly Wunderbaum trees hanging on the ceiling and the word "Sloth" is written in blood just above the bed.
  • In the level "Crystal Lake" you can find several locations from the Friday The 13th horror movies. Indeed, the name of the level itself references Camp Crystal Lake, the setting of many films in the series.
  • There is one gag available only in the Blood shareware that did not make it to the retail version of the game. During the first mission (E1M1) on the second floor of the Mausoleum there is an embalming room with a conveyor belt and a furnace. Among the items in this room are the "drips" that one would find in a hospital. Some a filled with what can only be blood. In the shareware version if one activates the blood drip one hears Caleb draw a big slurp, and exclaim "Aaah, tastes like Kool-Aid." This line was dropped from the Retail version, most likely due to copyright issues. Thus when Caleb takes a drink we only hear the slurping sound effect, and the subsequent "Aaah."
  • Axe-wielding zombies say "Brains" or "More Brains" and there are dormant zombies found in metal drums. These are all references to the Return of the Living Dead films.
  • A sign in E1M1 says "Welcome to Morningside Funeral Home" with the Morningside crossed out with spraypaint and replaced with "HELL." The name "Morningside" is likely a reference to the antagonist's name from the Phantasm movies.
  • In E1M1, if you try to use the sink, Caleb says "out, out, damned spot!" It is a reference to Lady Macbeth washing her hands of blood in Shakespeare's play Macbeth.
  • In E1M2 the train station is called Central Miskatonic, a reference to H. P. Lovecraft's works.
  • The train in E1M3 has the name "Phantom 666" emblazoned on the side, a reference to the "Number of the Beast" 666 in Biblical prophecy.
  • When you have the Incinerator equipped, Caleb will occasionally remark "I love the smell of napalm in the morning," a reference to Apocalypse Now.
  • In E3M2, enter the wine cellar and Caleb will comment on a certain barrel "A cask of Amontillado!" Edgar Allen Poe wrote a short story with the same name. Destroy the barrel and you'll find several sawn off limbs and body parts inside.
  • In the secret level "Butchery Loves Company" you can find a hidden area with a Duke Nukem arcade machine. Caleb will remark "I don't have time to play with you," a corruption of one of Duke's many one-liners.
  • Caleb's opening line "!" is lifted out of Army of Darkness.
  • One of the lines spoken by Caleb while massacring enemies is "Da-da-da-dat's all, folks!", a reference to the famous closing line from Warner Bros. cartoons, as delivered by Porky Pig.
  • And if you 'activate' Eric Draven's gravestone on the first level of Blood, Caleb will say 'Nevermore'. As in "Quoth the raven: 'nevermore' " of course, from Edgar Allan Poe's poem "The Raven".
  • In one further piece of homage in this densely referential work, on the second page of the "default keys" reference, characters from Blood will comically re-enact gameplay from Pac-Man, Asteroids and Donkey Kong.


The shareware version of the game contains many things that are not present in the full version, such as mushrooms that cause you to become delirious. The shareware levels are also slightly different in the full version. For example: E1M2 has been updated to include civilians which are not present in the shareware.


The name Tchernobog means black god (crno bog) in Slavic dialect. It is a pagan deity dated from ancient 12th century Slavic religion.


Wal-Mart required special editions of this game to be made before they would sell it. Identical to the original game in most aspects, they toned down the gore and removed any nudity.
