A codex (often pluralised as codexes by Games Workshop, though the grammatically correct pluralisation is codices), ^[1] 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 Until superseded by newer versions, the 3rd edition and later codexes remained valid for the newer editions of Warhammer 40,000. Games Workshop no longer produce campaign or battlezone codexes, instead releasing 'expansions'. 'Codex' is now a term solely used for army books.

The rules for all models from 7th Edition onwards have been produced as datasheets. These are normally a concise page containing all the necessary rules for a model or unit. A complete and comprehensive list detailing all the datasheets available for each faction is available on the Datasheet (Warhammer 40,000) Wikipedia page.

The introduction of 8th edition saw a large rules overhaul, and all prior codexes were rendered obsolete. On release, 8th edition introduced Indexes to introduce rules for all their armies, before again eventually releasing individual codexes. As with before 8th edition, codexes remain valid until superseded by newer versions (currently the oldest valid codex is Codex: Grey Knights - 8th Edition).

All codexes 6th Edition and prior contained:

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.

For 7th Edition Games Workshop overhauled the basic codex layout, 8th edition continued the same layout as such:

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.
In 7th edition datasheets contained the complete rules and points values needed to field a unit and a picture of the model from the Citadel Miniatures range, along with a description of the unit, as per the old bestiary.
In 8th edition a datasheet contains the complete rules for fielding a unit including power level and keywords. The points for matched play have been moved from the datasheet to the Appendix.
Appendix - In 7th edition this contained 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.
In 8th edition this became: weapon profiles, battle-forged rules (such as subfaction traits and stratagems), warlord traits, relics, psychic powers, tactical objectives and finally matched play points values for units and weapons.

Rules for models produced by Forgeworld are available as part of the Imperial Armour series of books, also published by Forgeworld.

Army Codexes[edit]

The range of codexes is regularly updated with new editions of armies and occasionally new army codexes. However, all codexes prior editions of Warhammer 40,000 are still valid in the current edition, unless a later version has replaced it. Upon the launch of 8th Edition, all codexes 7th Edition and prior were invalidated due to a rules overhaul and therefore incompatibility. On launch they were replaced with Indexes to provide compatible rules.
