[[File:H2 modding sworda.jpg|thumb|Through modding, the player wields two [[Energy Sword]]s at one time which is not possible in normal gameplay.]]

'''Modding''' is the practice of altering a video game by modifying its program code or game resources. This can include anything from simple texture or palette swaps to the creation of entirely new maps, features, or gameplay mechanics. Some mods directly alter in-game files, while others run independently and manipulate the game’s memory at runtime.

Due to its frequent association with cheating, modding is strictly prohibited on [[Xbox LIVE]] and within the '''Project Cartographer''' application for '''Halo 2 Vista'''. The use of a '''modded Xbox''', modified game clients, or unauthorized tools while connected to Xbox LIVE or PC public services may result in the immediate '''termination or banning of your account'''.

Modding within the ''Halo'' series is possible across both PC and [[Xbox 360]] platforms, but only when disconnected from Xbox LIVE services. ''[[Halo Custom Edition]]'', a PC port of ''[[Halo: Combat Evolved]]'', was specifically released with support for user-created content and modding. Additionally, ''[[Halo: The Master Chief Collection]]'' on PC allows players to disable anti-cheat protections at launch, enabling mod support at the cost of disabling Xbox LIVE functionality such as multiplayer [[matchmaking]].

Modding typically involves editing the [[Blam engine]]—the core engine used throughout many ''Halo'' titles—using external tools like '''Assembly''' or '''Mr. Mohawk''' to manipulate engine behavior and assets.

==Mod compatibility by game==
Mod support for ''Halo'' titles depends depending on the game and platform in question - notably, [[Xbox One]] games have very little modding support.

== Modding Tools ==
=== Assembly ===
[[File:AssemblyProgram.png|thumb|200px|Assembly's Home Screen]]
[[File:assembly_smg.png|thumb|200px|Modifying the '''SMG''' in ''Halo 2: The Master Chief Collection'' to fire '''Sniper Rifle''' rounds, achieved through [[Blam engine]] modifications. This is not possible through standard gameplay mechanics.]]

'''Assembly''' is a powerful modding tool designed for real-time editing across multiple ''Halo'' titles, including:
* ''Halo: Combat Evolved''
* ''Halo 2''
* ''Halo 3''
* ''Halo 3: ODST''
* ''Halo: Reach''
* ''Halo 4''

It allows users to modify in-game [[tags]] and values while the game is running, enabling deep customization and gameplay alterations not possible through normal means. Assembly supports real-time editing for ''Halo 2'', ''Halo 3'', and ''Halo: Reach'', and as of the latest update, also supports ''Halo: Combat Evolved''.

* '''Alteration''' - Tag editing tool for Halo 3 (similar to Assembly)<br>
* '''Liberty''' - Campaign Game Save Editor
* '''Halo Signer''' - GPD Resigner
* '''Mr. Mohawk''' – An early [[Tag]] editor primarily used for ''Halo 2 Vista''. Compared to [[Assembly]], it lacks modern features such as dropdown menus and real-time editing. All changes require restarting the game to take effect. Mr. Mohawk required editing offsets and magic values, making it more complex and less accessible for casual users.

== By game ==
=== Halo: Combat Evolved ===
[[File:Flying Warthog.jpg|thumb|200px|A flying Warthog in Halo Custom Edition.]]
Halo Custom Edition, an expansion to Halo PC, allows users to load and play user-made maps. Because all of the game's assets are stored as "tags" in map files, virtually everything that isn't part of the core game engine can be altered by a mapmaker. This, as one might expect, includes core map geometry, AI scripts, map scripts, textures, weather and skybox effects, sounds, [[weapons]], and [[vehicles]]. This system, combined with the availability of programs that extract tags from official [[campaign]] maps, makes it possible for mapmakers to create custom single-player campaigns, complete with [[cutscene]]s.<ref>[http://www.modacity.net/forums/showthread.php?22692-Lumoria-Episode-1-Released '''Modacity:''' Lumoria Episode 1 Released]</ref>

"Hacks" are technically another form of modding. Hacks generally take the form of third-party programs that a user activates after starting the game. They operate by [[Wikipedia:Cheating in video games|reading and editing the game's working memory]]. Hacks usable by clients include aimbots, sightjacking programs,<ref>[http://www.modacity.net/forums/showthread.php?11261-App-Sightjacker-for-1.04-1.07-1.08-1.09-PC '''Modacity:''' &#91;App&#93; Sightjacker for 1.04/1.07/1.08/1.09 PC]</ref> third-person point-of-view<ref>[http://hce.halomaps.org/index.cfm?fid=2645 '''Halomaps.org:''' Halo Third Person Fov]</ref> and flycam<ref>[http://hce.halomaps.org/index.cfm?fid=997 '''Halomaps.org:''' Halo FlyCam]</ref> utilities, [[heads-up display]]-disabling programs,<ref>[http://hce.halomaps.org/index.cfm?fid=2910 '''Halomaps.org:''' Halo Screen Options]</ref> texture modifications, name hacks,<ref>[http://hce.halomaps.org/index.cfm?fid=3246 '''Halomaps.org:''' Player Name Hack]</ref> and draw distance changers.<ref>[http://hce.halomaps.org/index.cfm?fid=3478 '''Halomaps.org:''' Clipping Distance Changer]</ref> [[Host]]s can use a wider variety of hacks without causing desynchronizations; these include dedicated server administration tools, weapon mods, hacks that can change individual players' properties on-the-fly,<ref>[http://www.modacity.net/forums/showthread.php?22594-rec0-s-Server-App-for-Halo-CE-1.09 '''Modacity:''' rec0's Server App for Halo CE 1.09]</ref> and even a tool that recreates ''[[Halo 3]]''<nowiki/>'s [[Infection]] mode.<ref name="igbrains">[http://hce.halomaps.org/index.cfm?fid=4314 '''Halomaps.org:''' IG-brainz V1.50]</ref>

Mods and hacks can be used to gain access to retail-only gametypes in the trial version of Halo PC. Programs exist that can convert retail-only maps into demo-compatible maps.

=== Halo 2 Xbox===
[[File:Ascension Modded.png|thumb|The map [[Ascension]], modded to look like an island.]]
It is possible to modify maps that are installed to the hard drive, such as [[Containment]] and [[Terminal (map)|Terminal]]. Because the ''[[Halo 2]]'' engine still uses the "tag" system from ''Halo: Combat Evolved'', it is therefore possible to edit any resource or asset in the map. However, mods will not synchronize for all players unless the person using the modded map is host. (So if a client modded Containment to make [[M7 SMG]]s fire [[M808 Scorpion]] rounds, and then they joined a game hosted by a non-modder, only the client with the mod would see Scorpion rounds come out of their SMG.)
=== Halo 2 Vista ===
Halo 2 Vista has software that allows RTE (''Real Time Edits'') to the campaign levels. This tool is [http://github.com/XboxChaos/assembly Assembly] ''"Not Related to the Level [[Assembly]]"''
This tool will work on Halo 2 Vista's Campaign along with a few other Halo games! The software does not have protection for Multiplayer maps, but instead hides all Tags from normal multiplayer .map files and puts them in a single file.
RTE's Allow the Game ([[Halo 2 (Windows Vista)|''Halo 2'' for Windows Vista]]) to be open while the mods are injected/poked into the game by editing values!
The mods are removed when you leave the Mission/Multiplayer! Although you can make SPPF patches with Assembly then later you can use an SPPF Patcher to apply them to the default .MAP files! <small>MAKE BACKUPS OF YOUR .MAP FILES, THEY COULD CORRUPT!</small>

== Cheating With Assembly or Tag Editor's. ==

With the release of '''Halo 2 Online''' under the '''Project Cartographer''' initiative, '''tag editing or BLAM engine modification on public servers is strictly prohibited.'''

Players are permitted to use '''Tag Editors''', '''Cheats''', '''Mods''', or '''BLAM Modifiers''' in:
* '''Private online games''' (Note: Project Cartographer's Anticheat is disabled in these matches)
* '''Solo Campaign'''
* ''Self-Hosted Dedicated Servers''

An advanced anticheat system is actively enforced to ensure that players who cheat in online public matches will receive a '''permanent ban'''. There is no easy way back—cheaters will stay banned!

=== Halo 3 ===
Console-based mods became very widely-available in ''[[Halo 3]]'', thanks to the development of the [[File Share]] and other ways of transferring user-created content. Though modding on the scale of Halo Custom Edition cannot be done without a devkit or a modded console, user-created Files can be altered using simple utilities to produce unusual effects.

[[Bungie]] does not allow the uploading of modded map or game variants to one's File Share, nor do they allow the uploading of modded [[Theater|film]]s, Film Clips, or screenshots. However, they do allow the uploading of un-modded Screenshots and Films showcasing modded map and game variants. After viewing a Film or Film Clip, the map and game variants from that Film are stored in a player's Recent Maps and Recent Gametypes; this allows players to share modded maps and gametypes by simply sharing un-modded Films of those gametypes on those maps.

==== Jtag/RGH/Devkit mods ====
Jtag/RGH/Devkit mods are essentially limitless. Any object in any map can be altered to do anything. Examples include:
*The development of entirely new weapons, such as "mind powers".<ref name="yt-mind-powers">[http://www.youtube.com/watch?v=kIIkNRaGvdA '''YouTube:''' My Very Last Mod: Halo 3 Mind Powers]</ref>
*Altering weapons and grenades to fire different projectiles, or to spawn various objects (like vehicles, active [[power drain]]s, or Spartan bipeds) when fired.{{Ref/Reuse|yt-mind-powers}}<ref name="yt-valhalla-devkit-1">[http://www.youtube.com/watch?v=AIiQ5Xf4JK8 '''YouTube:''' Halo 3 - Valhalla DEV KIT Mods PART 1 of 2]</ref><ref name="yt-valhalla-devkit-2">[http://www.youtube.com/watch?v=zJFZoLns4es '''YouTube:''' Halo 3 - Valhalla DEV KIT Mods PART 2 of 2]</ref>
*Editing Warthogs so that their tires kick up sniper shots instead of dirt.{{Ref/Reuse|yt-valhalla-devkit-2}}
*Disabling all kill barriers and invisible walls in a map.{{Ref/Reuse|yt-valhalla-devkit-2}}
*Changing map textures.<ref>[http://www.youtube.com/watch?v=EtT5uukENzw '''YouTube:''' Halo 3 Modded Map - Snow on Valhalla!]</ref><ref name="yt-get-a-jtag">[http://www.youtube.com/watch?v=OwryBRK3Lww '''YouTube:''' Get a JTAG, Have Fun.]</ref>
*Biped swaps (such as playing as a [[Jiralhanae|Brute]] in Campaign, or turning [[UNSC Marine Corps|Marine]]s into Spartans).<ref>[http://www.youtube.com/watch?v=GzpKvDAm9Vw '''YouTube:''' Halo 3 Dev Kit Mods On Retail Console- Campaign Biped Swaps]</ref>
*Playing on the main menu.<ref>[http://www.youtube.com/watch?v=ljkyL7ossWg '''YouTube:''' Halo 3 - Playing on the main menu]</ref>
*Altering the movement speeds of map scenery, such as the wheel on [[Last Resort]].{{Ref/Reuse|yt-get-a-jtag}}
*Altering bullet physics; for example, making a Sniper Rifle score headshots through walls, even when missing a target by several feet.{{Ref/Reuse|yt-get-a-jtag}}
*Attaching a Warthog Turret to another Warthog Turret, attaching ''that'' turret to a detached Machine Gun Turret, and then having a player man each turret, such that one player is carrying another player who is carrying another player.{{Ref/Reuse|yt-get-a-jtag}}

==== Map variants ====
[[Maps|Map variants]], for example, can be created in [[Forge]] and then modded. Forgeable objects can be replaced with any non-terrain objects in a map. Through this method, a variety of development leftovers can be added to maps. These include partially-Forgeable objects from the [[Halo 3 Epsilon]] build ([[Covenant watchtower]]s<ref name="yt-50-chiefs">[http://www.youtube.com/watch?v=0TJagZAwmZU '''YouTube:''' Halo 3 Snowbound MOD (X360) 50+ Master Chiefs & MORE????]</ref> and [[Shade]]s), unused game objects (like [[M41 SPNKR|rocket launcher]] ammo cases and [[Type-33 needler]] ammo pickups on [[Blackout]]), and unused map-specific objects (like a hologram of the [[Installation 00|Ark]] on [[Guardian (map)|Guardian]]). Some vehicles cannot be Forged onto a map, but can be modded onto the map; examples include [[AV-14 Hornet|Hornet]]s and [[Banshee]]s<ref name="yt-70-banshees">[http://www.youtube.com/watch?v=OmTdoTPB_so '''YouTube:''' Halo 3: Mod "70 banshees"]</ref> on [[Narrows]], and [[Warthog]]s on [[The Pit]]. Warthog turrets can be placed independently of a Warthog. Map-specific objects (like [[Sandtrap]]'s [[M313 Elephant]]s and [[Guardian (map)|Guardian]]'s birds) can be created and moved using modding. Objective objects, such as [[Type 14 Magnetic/Anti-Tank Mine|bombs]], [[H3:Skulls|skulls]] and [[flag]]s, can be modded onto a map, in which case they are available for use in all gametypes. Inactive bipeds ([[Spartan]]s, [[Sangheili|Elite]]s, and [[Monitor]]s)<ref name="yt-guardian-mod">[http://www.youtube.com/watch?v=C9_86hXtIR4 '''YouTube:''' Halo 3 Guardian mod]</ref> can also be placed on maps.{{Ref/Reuse|yt-50-chiefs}}<ref name="yt-snowbound-mod">[http://www.youtube.com/watch?v=yALeahP4hu0 '''YouTube:''' Snowbound mod]</ref> Even large pieces of map scenery, such as the {{UNSCShip|Aegis Fate}} on Sandtrap,<ref name="yt-h3-frigates">[http://www.youtube.com/watch?v=yaaglZ69qpQ '''YouTube:''' Halo 3: Sandtrap Modded map: 2 Frigates!]<div style="margin-left:2em">''Forward Unto Dawn'' name visible on Frigate 35 seconds into the video.</div></ref> can be modded, though such mods are only visible to the host.

Gametypes also have the .blf (Blam File Header/Blam Library Format) header, which stores information such as the Variant Name, Variant Author, and Variant Description. These fields may be edited to hold any value, including censored terms and control characters, and displayed in the menu. Control characters allow symbols and icons to be inserted into the map's description. An XML-like syntax allows colored text, the current date and time (updated in real-time), and the name of a viewer's gamertag to be inserted into the description. It can become difficult for any information about the file to be verified locally, including the original author.

==== Screenshots and Films ====
Programs allow the armor worn by players in Films to be changed. Any armor permutation may be substituted, including [[RECON-class Mjolnir|Recon]] and [[Bungie Armor]]. Screenshots can be replaced with any image.

=== Halo: Reach ===
Players in ''Halo: Reach'' have been able to use offline mods to unlock armor pieces prematurely,<ref>[http://halo.bungie.net/Stats/Reach/FileDetails.aspx?fid=10555626 '''Bungie.net: Halo Reach Files:''' Haunted Helmet Mod] (''film'')</ref> "fly" [[UNSC frigate]]s in [[Reach:Long Night of Solace|Long Night of Solace]]<ref>[http://halo.bungie.net/Stats/Reach/FileDetails.aspx?fid=9655390&player=JumboDragonfly '''Bungie.net: Halo Reach Files:''' Flying The Frigate] (''film clip'')</ref> (by "attaching" the Frigates to [[Sabre]]s), "fly" the [[Pillar of Autumn]] on its titular level (using the same method, but with a Banshee),<ref>[http://halo.bungie.net/Stats/Reach/FileDetails.aspx?fid=7971331 '''Bungie.net: Halo Reach Files:''' Flying The Pillar of Autumn] (''film clip'')</ref><ref>[http://halo.bungie.net/Stats/Reach/FileDetails.aspx?fid=8145865 '''Bungie.net: Halo Reach Files:''' [Hack<nowiki>]</nowiki> 戦艦オータム - 操縦 ☆] (''film clip'')</ref> pilot [[Seraph]]s and other normally-unusable vehicles,<ref name="reach-secret-vehicles">[http://halo.bungie.net/Stats/Reach/FileDetails.aspx?fid=9905110 '''Bungie.net: Halo Reach Files:''' Secret Vehicles] (''film clip'')</ref><ref>[http://halo.bungie.net/Stats/Reach/FileDetails.aspx?fid=8407846&player=JumboDragonfly '''Bungie.net: Halo Reach Files:''' Flying The Transport Jet] (''film clip'')</ref><ref>[http://halo.bungie.net/Stats/Reach/FileDetails.aspx?fid=8123935&player=JumboDragonfly '''Bungie.net: Halo Reach Files:''' Flying The Longsword] (''film clip'')</ref> use [[Kig-Yar|Jackal]] shields{{Ref/Reuse|reach-secret-vehicles}} and other normally-unusable items, and use a [[Bungie]]-exclusive font glyph (the Bungie logo) as a Service Tag.

Devkit mods also revealed hidden functionality in the Beta. One could join and host Local and [[System Link]] games, and break into the [[custom game]] lobby via the [[Theater]] lobby. (Gametype settings were entirely non-functional, though whether this is due to the Beta or due to the devkit mods is unclear.) As in ''Halo 3'', weapons could be altered to fire different projectiles or spawn new objects, like vehicles.{{Ref/Reuse|yt-get-a-jtag}}

== Bungie takes action ==
{{main|Archive:Bungie With Teeth}}
[[File:Suspended.jpg|thumb|350px|The consequence of using mods online]]
This has become such a widespread problem in the [[Matchmaking]] system that [[Bungie]] was forced to resolve the problem by releasing auto-updates which ban hackers from the system and terminate their accounts. Bungie has banned thousands of players and is working to clean up the rest, earning in the process the moniker 'Banhammer.' Several sites offer a list of cheaters and hackers.

Although there used to be several ways to mod, Xbox Live and Bungie have collaborated to rectify the programming mistakes and prevent the game from being modded as much. They are also reinforcing much stricter punishments for cheaters, such as instant bans and longer suspensions.

==''Halo 5: Forge''==
The [https://www.youtube.com/watch?v=1XlriRF5ogA Exuberant] mod tool by YouTuber GameCheat13 allows players to:
*Customize [[Armor customization (Halo 5: Guardians)|armor]]/ weapons without the need for [[List of REQ cards|REQs]] or a console to make changes
*Change the player [[Heads-up display|HUD]] to a HUD from the [[Campaign]] (ex. [[Frederic-104]]'s [[:File:H5G-GEN2 Centurion BIOS.png|HUD]], etc.)
*Change player field-of-view
*Change player Spartan ID fields ([[assassination]]s, announcer, and emblem)
*Enable a local [[H5G:Forge|Forge]] server for testing AI

You cannot be banned for using Exuberant unless you are using options from the "Local Only" tab. However, enabling AI in forge online will result in a ban.

Because ''Halo 5: Forge'' does not have Arena or [[Warzone]], player progress on Xbox One will not be harmed.

==''Halo: The Master Chief Collection''==
Modding is officially supported by ''[[Halo: The Master Chief Collection]]'' for all games within, including ''[[Halo: Combat Evolved]]'', ''[[Halo 2]]'', ''[[Halo 3]]'', ''[[Halo 3: ODST]]'', ''[[Halo: Reach]]'' and ''[[Halo 4]]'', as well as the multiplayer of ''[[Halo 2: Anniversary]]''. While anticheat is disabled, players cannot enter matchmaking and progression progress is not saved to the ''[[Halo Waypoint]]'' servers. However, players will not be punished for any mods run while anticheat is disabled. Some mods such as menu background replacers can be run with anticheat enabled without penalty.

To mod ''The Master Chief Collection'', there are several programs available, both official and unofficial. Due to the games in the collection being those available for the Xbox 360, Assembly is compatible with ''MCC'' files and tags. A full list of useful software is below;
*''[https://github.com/XboxChaos/Assembly/releases/tag/2019.12.20-Updater Assembly]'' | ''[https://www.se7ensins.com/forums/threads/halo-mcc-assembly-basic-how-tos-pc-only.1880011/ How to use Assembly for MCC.]''  - Used for editing tags in-game within ''Halo 2'', ''Halo 3'', ''Halo 3: ODST'', ''Halo: Reach'' and ''Halo 4''.
*''[https://www.gildor.org/en/projects/umodel UE Viewer]'' - Useful for extracting icons, meshes and textures from the ''Unreal Engine 4'' menus of ''The Master Chief Collection''.
*''[https://github.com/Lord-Zedd/MCCTexturePackDumper/releases/tag/1.0 MCC Texture Pack Dumper]'' - Useful for extracting texturepack files from ''The Master Chief Collection'' containing many UI elements such as emblems, [[Nameplates/Halo: The Master Chief Collection|nameplates]] and more.

==''Halo Wars'' series modding==
[[File:HWDE Spectre Mod.png|thumb|A {{Pattern|Wuzum|Spectre}} modded into ''Halo Wars: Definitive Edition''.]]
Thanks to the PC releases of ''[[Halo Wars: Definitive Edition]]'' and ''[[Halo Wars 2]]'', modding can also be conducted on these games - however no official mod tools exist for these games. Nonetheless, a number of community mod tools have been developed to assist in creating custom content for ''Halo Wars''. 

Within ''Halo Wars: Definitive Edition'', modding can be used to implement custom infantry, vehicles and buildings, leaders, techs and other settings. New additions can range from simply tweaking what already exists in the ''Halo Wars'' files to adding in characters and vehicles from other ''Halo'' games to adding completely custom models. 

A number of community resources exist to enable easier modding of ''Halo Wars'', listed below.
