Blood Code is a flexible Class system in Code Vein. Instead of having regular starting classes and locked abilities, Code Vein provides freedom by allowing players to level up different Blood Codes simultaneously, and swap them on the fly. Blood Codes affect the player character's actions, Gifts (Magic) available, and player Stats providing optional approaches for difficult areas or bosses and the capability to master multiple builds. At the start of the game, players will start off with three Blood Codes, Fighter, Ranger, and Caster - and as the game progresses you will be able to acquire other Blood Codes from NPCs or from exploration.
Using Blood Codes
Blood codes in Code Vein are categorized as classes. As mentioned, players start off with three Blood Codes: Fighter, Caster, and Ranger - and as the game progresses you'll be able to acquire more Blood Codes. Code Vein introduces a unique mechanic on how Blood Codes work where players are able to swap and equip their desired code that fits their play style on the fly. This provides a versatile option which can turn the tides of a battle. Not only do Blood Codes allow the player to harness its unique Gifts, but swapping a Blood Code also changes the player's stats and the ability to wield different Weapons and Blood Veils.
Gifts and Blood Codes
For each Blood Code, it contains various Gifts that benefit its code. Not only can a player change their Blood Codes, but players can also personalize and equip any desired active and passive Gifts that suits their play style. It is important to take note that most of the Gifts have stats requirement, so some Gifts cannot be equipped with certain Blood Codes.
Code Vein Blood Codes
Revenants possess special powers known as "Blood Codes." Depending on the specific blood code, a revenant's stats will differ. To view these stats, select the currently equipped blood code on the menu screen.

As of this point in time, the missing Blood Codes are Pollux(from the Frozen Empress DLC), and the ones from Lord of Thunder(Vali, Orion, and Perseus).

Got the good ending and the Hades code so not sure what happened but I didn't get queen.

Important piece of information. If you collect and restore all the vestige fragments of a blood code core you didn't collect, then go to NG+, then go and get the vestige core, you won't need to get the vestige fragments for that blood code. This was nice for me since I got all the fragments for Scout, but forgot to get the core before going to NG+, so when I got the core in NG+ I didn't need to get any of the other vestige fragments to unlock all the gifts.
Let me guess. The DLCs will add the Zeus, Poseidon, Ares, Odin, Thor, Freya/Freyja, Baldur, Ra, Anubis, Osiris, etc. Blood Codes. Will there be a Kratos Blood Code?

Having a little trouble unlocking Artemis. I defeated both bosses but no blood code.

i have all the codes listed here but dont have the achievement for all the codes, is there one missing from this list?
All balance calculations that are written have been done with an unknown Blood Veil which is bloating the number while also causing it to be inaccurate. Revising to show Base Balance of the Blood Code instead.
To Get all Blood Codes, you need two playthroughs, one with all memories returned to successors, and one with none at all: just go through the gate after defeating the bosses.

Also the Scout Code is missing (it belongs to Naomi). I dunno how to get it, it must be somewhere in the depths though

Damn I wish there was more Information on The Harbinger BloodCode

The prometheus class is already pretty fun, from the trial I played!
You get the "breath" core after successor of the breath but you can not use it? Did they forgot about this? You get queens breath and others the by not restoring.
