The Runtime software is currently not produced for these platforms, but may be made available if demand warrants. If you are interested in viewing or serving Runtime content on these platforms, please contact udn@epicgames.com.

Please note that regardless of Runtime client and server availability, the content production software, including the UnrealEngine2 Editor and the UnrealScript scripting language compiler are available for PCs running Windows only.

Downloading the Runtime

If downloading through your web browser, it will likely ask you what it should do with the file. Click Save File or Save this program to disk, note the location where you're saving it to, and click OK.

Installing the Runtime

  • Once your download completes, if the dialog provides you with the option to Open or Launch File, click that option. If not, click on Start, Run..., Browse... and navigate to where you saved the installation file. Double-click on the file, then click OK.
  • Click on Setup to begin the installation.
  • Once the installation files have uncompressed, you'll be presented with the UnrealEngine2 Runtime installation dialog. Click on Next to view the software licensing agreement (also online). You must agree to the terms to use the Runtime. If you agree, click on I Agree to proceed.
  • On the next screen, you can enter an alternative location to install the Runtime; the default is recommended. Click on Next to continue.
  • If you are installing more than one copy of the stock Runtime software, you should read the notes for the two Runtime association checkboxes. You may want to change one or both of the options.
  • Finally, click Next, then Install.
  • When the installation finishes, you can Launch the UnrealEngine2 Runtime, read the Release Notes (also online) or visit the UnrealEngine2 Runtime web site (this site).

Using the Runtime

  • To use the Runtime, launch it by either selecting Launch UnrealEngine2 Runtime from the final installer screen, or by selecting Start, Programs, UnrealEngine2 Runtime and clicking on Launch UnrealEngine2 Runtime.
  • The Runtime splash screen will appear, followed by the main menu. The Runtime comes with a simple example map for you to wander around and familiarize yourself with the Runtime's controls and view some of the most basic effects possible with the software.
  • Click on Load Map to open the level. Your mouse controls your viewpoint; this is called mouselook. Your keyboard controls your movement independent of your viewpoint, just as you are able to walk while also turning your head to look around. Use the up and down arrow keys or W and S to move forward and backward. Use the left and right arrow keys or A and D to step left and right (not turn left and right, but rather move laterally; sidestep). Additionally, the F key toggles between flying mode and walking mode.
  • Pressing Esc brings up a menu where you can close the level and return to the main screen, access your settings, or quit the program entirely.

Configuring the Runtime

  • Based on your PC's hardware, the runtime will select a basic video and audio configuration. The various tabs on the Runtime menu screen allow you to modify these settings to adjust the tradeoff between rendering quality and speed. For an examination of these options, please read EndUserEngineConfiguration?.
  • Additional rendering options are available by manually editing the Runtime's configuration files, such as OpenGL support, software rendering for PCs with fast CPUs but slow video cards, video refresh synchronization, and more. For an examination of these options, please read EndUserVideoConfiguration?.

Creating your own Runtime Content

  • You can launch the UnrealEngine2 Editor (UnrealEd) by selecting Start, Programs, UnrealEngine2 Runtime and clicking on UnrealEngine2 Editor.
  • The UnrealEngine2 area of UDN contains full documentation on the level design process. WhatToReadFirst is an excellent place to start.
    • Additionally, the UDN ExampleMaps list many small, sample levels you can download to see how certain features and functions are implemented. Make sure to download the "Runtime" versions of each one.
  • Technical documentation on customizing the Runtime's interface, creating new UnrealScript code and more is underway.
  • Visit the unofficial BeyondUnreal forums for the Runtime, at http://forums.beyondunreal.com/forumdisplay.php?f=438

Reporting Bugs

  • As with any cutting-edge technology, there may be instances that cause the Runtime software to crash. In these corner cases, a dialog will present itself with a Submit Bug Report button. We would like to encourage you to report these errors using this button. Once is enough.
  • If you possess a copy of the Windows PC version of the video game Unreal Tournament 2003, we would sincerely appreciate you attempting to repeat the actions that cause your Runtime software to crash, using UT2003, to help us determine if it is a Runtime-specific, or general engine issue.

Known Issues

  • TODO


  • While the extensive network capabilities of the Runtime are not exposed in the menus, they are fully functional. We are running two multiuser servers using the example level. To try them out, press ` (backquote) to drop down the console, and type in open runtimemaster.epicgames.com:7777 or open runtimemaster.epicgames.com:8888 to connect to one of the servers. Once you connect, you will be able to move around and see other visitors (all represented by cubes). You can press T and enter text to speak to others in the world.
