Codex (Warhammer 40,000)

Example early 3rd edition Codex (Imperial Guard) Each codex had its own lettering style for the title.

Example late 3rd edition Codex (Imperial Guard) All of these longer codexes had a standard black border and common title style.

Example 4th edition Codex (Space Marines) All codexes had a standard grey metal-effect border and common title style. 5th Edition Codexes have continued this styling.

A codex (often pluralised as codexes by Games Workshop, though the grammatically correct pluralisation is codices), in the Warhammer 40,000 tabletop wargame, is a rules supplement containing information concerning a particular army, environment, or worldwide campaign.

Codexes for particular armies were introduced for the second edition of the game. The third edition rendered these obsolete, and a new series began, including introducing codexes for battlezones and campaigns.

Until superseded by newer versions, the 3rd edition and later codexes remain valid for the newer editions of Warhammer 40,000 (currently the oldest valid codex is Codex: Chaos Space Marines - 6th Edition). Games Workshop no longer produce campaign or battlezone codexes, instead releasing 'expansions'. 'Codex' is now a term solely used for army books.

A codex normally contains:

• Background - Information about the force and its place in the Warhammer 40,000 universe. This includes artwork, short stories, and copies of fictional documents from the future.
• Bestiary - A description of the units, characters and vehicles that can be chosen for use in a battle. This includes their characteristic values, information on their weapons, and any limitations on their use, as well as background information on the unit. The army's special psychic powers (if any) and wargear is also listed here, showing the rules for each item, as well as any legendary artifacts the army may use.
• Hobby section - Information on collecting, building and painting an army from the codex. This features outstanding example models painted by veteran hobbyists and Games Workshop's 'Eavy Metal team.
• Army list - The items in the bestiary are arranged by type and given a points value, with more powerful units costing more points, so that battles are fought between balanced armies. Options are also given here along with their cost.

In June 2013 Games Workshop introduced new codex supplements. Codex supplement books are additional rules and options for an army's standard Codex and contain additional background. These options often include new relic lists, warlord traits, and Special Characters to be used within the detachment. A detachment using a codex supplement may also ally with the parent codex, and vice versa. The parent Codex is required to use the supplement. For example, Iyanden is a supplement to Codex: Eldar that allows Craftworld Iyanden specific rules to be used in an Eldar army.

In June 2014 Games Workshop redesigned the basic layout of the codex, as standard for 7th Edition. New 7th Edition codexes will now contain:

• Background - Information about the force and its place in the Warhammer 40,000 universe. This includes artwork, short stories, and copies of fictional documents from the future - (The same style as before).
• Showcase - This is the old Hobby Section that now contains just pictures of the Citadel Miniatures; painted by Games Workshop's 'Eavy Metal team.
• Army List - This contains datasheets for every unit and a wargear list. A datasheet contains the complete rules and points values needed to field a unit and a picture of the model from the Citadel Miniatures range. It also includes a description of the unit, as per the old bestiary.
• Appendix - This contains a complete, detailed list of all the army's weapons, special rules, psychic powers, warlord traits and any detachments or tactical objectives it may have. It also contains a quick reference sheet at the very back.

A complete and comprehensive list detailing all the datasheets available for each faction is available on the Datasheet (Warhammer 40,000) Wikipedia page. This compiles a list of datasheets available throughout different Games Workshop publications that many not be included in the parent codex.

Expansions/Supplements

Example 4th edition expansion (Apocalypse) This style was carried over onto 5th edition expansions.

A supplement is for use in standard games, though they may significantly alter the game (such as by adding super-heavy vehicles to normal games, or the many supplemental battle missions). An expansion is normally a different way to play the game (such as the large scale battles of Apocalypse, or the different campaign expansions). Supplements are considered part of the main rules available in normal games. Expansions must be agreed upon by all players before the game begins, to see if that set of expanded rules are in use. Campaign books often contain additional rules to fight specific battles between specific armies, it will often include rules updates to those armies including new datasheets, formations and detachments. Boxsets contain rules for two specific formations of two factions.

Digital Releases

Dataslates

Dataslates are a way to digitally add new rules and new units to the game. For Characters, Dataslates give the full rules and points to include that character in the listed factions.

Formations are a group of units that work together in a specific battlefield role, and they are taken as a separate formation detachment (the alliance rules are in place for allied formations). For example, a primary detachment from Codex: Space Marines could take the Tau Firebase Support Cadre formation and it would count as a battle brother, however, the Space Marines would not be able to take a tyrannic formation (as tyranids can not be allies). NOTE: Multiple formation detachments may be taken.

Apocalypse units and formations follow the rules in the Apocalypse Rulebook.

Altar of War

Altar of War Missions can be used instead of the Eternal War missions in the main rulebook, however the named army's Altar of War missions can only be played if that army is one of the primary detachments in the battle. For example, a battle is being fought between Tyranids and Imperial Guard - the Imperial Guard player has also brought along a baneblade. They can either play the eternal war missions or choose to play/role on the tyranid OR Escalation Altar of War missions.

As of May 2015, White Dwarf has started to include new missions and scenarios in a new regular article known as Theatre of War. These missions can be played when agreed upon by the players instead of the standard rulebook missions. Some missions require one player to use an army of a specific faction (noted before the title of each mission when necessary). The issue number that the mission is printed in, is included in brackets.

Battlezone

Battlezone codexes were rules supplements that dealt with a specialised combat environment, instead of an army. There was only ever one produced. However, material in Codex: Catachans provides rules for jungle warfare. The concept of a Battlezone codex was replaced by Games Workshop's Expansions.

3rd Edition Events

The two event codexes were released in association with the 2000 and 2003 Worldwide Campaigns. These codexes provided background and special gaming rules for the event, along with four "supplemental army lists"; variant armies that required access to certain other Codices for use.
