The most convenient way to browse and search the source files is by using a dedicated class browser such as UnCodeX.

These sources are for reference only. Never attempt to compile default packages – that's not the way modding works with the Unreal engine. Instead, derive your own custom classes from the game's default classes and use an INT file to hook them into the game.

Unreal Tournament 3

Build 3487 

• Unreal Tournament 3 v1.0 Source (2.89 MB Download from UDN)

Build 3521

Unreal Tournament 2004

Note: BeyondUnreal download links are broken. Please update them here if you find alternate links.

Original UnrealScript sources and .u files compiled for debugging support (obtained directly from Epic Games). From build 3323 onwards, the scripts download includes the Onslaught Bonuspack (OnslaughtBP) sources.

The UnrealScript sources also include the Onslaught C++ source code and excerpts from engine C++ code for:

• Chain of events at level startup
• Chain of events when spawning actors
• ticking Weapons and WeaponFire (UT2003)
• Pawn animations
• team beacons for players and vehicles

Note: The debug .u files can only be used for exactly that: debugging your code. They will not allow you to connect to internet servers. Backup your original .u files before installing the debug packages to test your code and restore your original files if you want to play online games.

Unreal Tournament 2003

Original UnrealScript sources and .u files compiled for debugging support (obtained directly from Epic Games).

Note: The debug .u files can only be used for exactly that: debugging your code. They will not allow you to connect to internet servers. Backup your original .u files before installing the debug packages to test your code and restore your original files if you want to play online games.

Postal 2

Original UnrealScript source code (from Running With Scissors' web site)

Version 1407

• WinZip Self-Extractor: Postal 2 Version 1407 Sources (2.8 MB, download from Running With Scissors)

XIII

Version 839

• Complete source files including classes, textures: Undox script docs

Unreal and Unreal Tournament

Although you could easily extract the source code with UnrealEd, El Muerte provided downloads for the script source of these games:

• http://unreal.elmuerte.com/Unreal-Gold-ScriptSource.zip
• http://unreal.elmuerte.com/UT-436-ScriptSource.zip

Other Unreal Engine Games

The source files can be exported with UnrealEd's Actor Classes Browser (File -> Export All Scripts) but they might be incomplete in some UnrealEngine 2 builds due to missing subobjects in the default properties. This is one reason for Epic to make the UT2003 sources available for download.

Note that exported sources might not contain subobjects, but this isn't a problem for older engine builds like v436, because at that time subobject definitions in default properties were not supported.

Some compiler directives (those specifically pertaining to native code) are also often lost when decompiling the built-in packages instead of downloading the sources.

Also, some Unreal Engine based games have the source code removed from the shipped packages. America's Army and XIII are two such examples. When this is the case the Unreal Script code cannot be exported.
