3dfx patchMonolith 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.
CultistsThe 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 featuresOne 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 MaskDeath 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.
DevelopmentApogee 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.
ExtrasSome 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 indexOn June 28, 1997, Blood was put on the infamous German index by the BPjS. The game group contains more information about what this means.
InactivityWhen 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.
- 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.
- E1M1 the morgue has a sign saying "Welcome to Morningstone!" with the Morningstone crossed out with spraypaint and replaced with "HELL." This is a reference to a similar place in a H. P. Lovecraft novel.
- In E1M2 Caleb at one point says "out, out, damned spot!" A reference to Lady Macbeth washing her hands of blood in Shakespeare's play Macbeth.
- In E1M2 the train station is called Central Miskatonic, and the train has 666-PHANTOM emblazoned on the side. More HP Lovecraft.
- 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 catchphrase "I...live...AGAIN!" is lifted out of Army of Darkness.
- It is not known if this ever appears in the game, but on the Blood CD there is an audio file that has Caleb saying "That's all, folks!" in a fake Bugs Bunny voice.
- 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!
- 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.
SharewareThe 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.
TchernobogThe name Tchernobog means black god (crno bog) in Slavic dialect. It is a pagan deity dated from ancient 12th century Slavic religion. Also, compare Chernovoi [CHAIR-no-VOY] "bad, occult spirit" in Russian, or Domovoi, Russian for "a good spirit that lives at an inn or a person's house, and protects it from bad things, as long as the person is basically good." There is a Domovoi (in fact two of them, one with a large role who has blue fur, and the other with a small role who has discolored brown fur) in Quest for Glory IV. In medieval Russian folk tales, when the good housewife heard the house making creaking noises, these were supposed to be the sounds made by the mommy Domovoi's little tiny children. It was said to be a good idea for the housewife to throw down a heavy cloth on top of the place where the housewife heard the noises. The mommy Domovoi would then not be able to hear where her little children were, because the cries would be muffled. In exchange for telling the mommy Domovoi where her children were, it was said that the medieval Russian housewife could ask the mommy Domovoi any question at all, and would be able to count on getting a magically correct and complete answer.
Wal-MartWal-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.
