Epic Games provides not only a comprehensive multi-platform 3D engine to licensees, but also a vast array of support resources, ranging from a document-based wiki article site styled after the Microsoft Developer Network (MSDN) to community-driven dicussions via mailing lists with direct access to the Unreal Engine development team – all of which are fully archived and searchable.
With a paid Unreal Engine license, your team receives support for the course of your development project and for a 12-month period after shipping. The Unreal Engine support resources include
Hands-on Training
We provide on-site training for first time licensees – at your location for content creation training, and our location for engineering. We come to you to show your content team how to best work with our tools and content pipeline, and we invite your engineering staff to visit our Cary, NC offices to meet with our entire engineering staff to answer questions and provide overviews of current subsystems and the future technology roadmap. Depending on availability, our doors are open for visits throughout the development life of your project.
Unreal Developer Network support site – UDN
We realize that you have chosen an award-winning technology for your project, and we want to make sure that your teams have a full understanding of the tools available to them so that they can use the Unreal Engine to it's fullest potential.Email Support Direct from the Unreal Engine Developers
Support mailing lists are available for programmers and content creators, with all questions receiving direct answers from the Unreal Engine development team, as well as frequent participation by other teams using the Unreal Engine. For confidential questions, we are always happy to provide help via private email. At Epic, we don't employ any support intermediaries; we would rather provide information from the people who know it best. Teams receive support straight from the Unreal Engine development team – the folks who wrote the code and utilized the same tools that licensees use to ship amazing projects time and time again.
Tutorials, Example Content, and Technical Guides
UDN consists ofa vast, professionally-maintained online library of support materials, including hundreds of documents encompassing content creation tutorials, tools user guides, example files, programming technical guides, high-level subsystem overviews – all of which are fully archived and searchable. Licensees have access to hundreds of private pages of information; and nearly half of the documents on UDN are visible to the public!
Video Training Modules
Epic's close partner 3D Buzz provides a vast collection of video training modules with tutorials covering many topics such as level design, texturing, AI pathing, and importing various types of content from external tools. They also put together the Mastering Unreal Technology series of books.
International Support
All of the Unreal Engine tools are fully extensible to meet your needs, including full localization support. UDN documentation is actively translated as new pages are created and existing ones are updated. Email support is also available. We take pride in reaching out to developers all around the world.

Source Code and Example Content
Direct Source Control Access (Unreal Engine 3)
Teams licensing Unreal Engine 3 receive an account with direct access to Epic's Unreal Engine builds via their Perforce source control depot, for checking out our work in progress, obtaining bug fixes and code updates, and monitoring revision history to keep abreast of day-to-day development activity on the engine and its latest features. Epic also has a rigorous quality assurance process that creates monthy checkpoints of the latest changes to make upgrading as smooth as possible.
Code Drops (Unreal Engine 2)
Teams licensing Unreal Engine 2 may acquire snapshots of the latest codebase via code drops. These typically contain code used in shipping titles, as well as up-to-the-minute bug fixes.
