This article is the basic guide for downloading and installing Urban Assault and other official game files on modern computers. The contents here will be copied into a separate forum thread in future for a better accessibility.
Our website offers the most authentic and verified game files and content for Urban Assault and other UA contents. We also provide technical support and assistance for running the game on modern systems and hardware.
All files in the downloads section here are verified, fully authentic, and completely safe to use. Please read this section carefully first so there will be no mistake, and then move on to the installation or troubleshooting sections next.
Alternatively, if you want the most quick and stable solution for running the game on modern hardware without any additional workarounds or troubleshooting, then please scroll down and use the 'OpenUA Standalone Package' file!
2.1 Urban Assault:
(NOTE: This is the full original authentic retail copy of Microsoft Urban Assault as it was released in 1998. Therefore, it may require additional configurations and workarounds to properly install and play on modern hardware.)
(NOTE: Metropolis Dawn is the official expansion of Urban Assault. The expansion pack requires either 'Typical' or 'Full' installation of the original Urban Assault with full registry data on the machine before it can be installed.)
2.3 Urban Assault Trial:
(NOTE: Urban Assault Trial is the official demo version of Urban Assault. It was available for download at the official Microsoft Urban Assault website long time ago.)
2.4 AI Helicopter Patch:
(NOTE: This is a set of patched/debugged game executables that was designed to eliminate the 'AI Helicopter Glitch' that occurs on modern hardware in the original UA engine. OpenUA does not require this fix! For more information, see the article: AI Helicopter Glitch.)
2.5 OpenUA Standalone Package (HIGHLY RECOMMENDED):
(NOTE: OpenUA Standalone Package is HIGHLY RECOMMENDED for normal users who want a quick and stable way to play the game on modern hardware without further workarounds. This is a full standalone game package with the original game data (Urban Assault + Metropolis Dawn expansion pack) contents that requires no installation process, with the latest stable UA:Source files as well as other necessary configurations setup applied inside already. Please use 'UA_Source.exe' (not 'UA.exe' or 'Ua_xp.exe'!) and its variants to launch the game in the OpenUA engine.
If you are new in the community, and have problems determining which game files to download and/or had already experienced technical issues with the original UA files on your machines, then download and use this package. Also when using this package, please check the 'Package Description' Readme file first! Everything you need to know about the package is properly explained in there. This package now also contains the authentic and official German, French, and Japanese localisation files of Urban Assault. However, the in-game movie files in this package are only available in English version because they take up a large portion of the total game size.)
What is OpenUA:
2.6 OpenUA Standalone Package (Demo version):
(NOTE: This is the trial version of the game that has been fully configured to be played on OpenUA in a similar manner to the above full version of standalone package. Again, please check the 'Package Description' Readme file inside!)
The installation methods are generally straightforward. However, additional configurations and workarounds may be necessary on modern systems and hardware.
