    5 Installation

    5.1 Windows

    Launch the official MSUADEMO.exe installer file with the administrator privileges. It is highly recommended to set the compatibility mode of the executable to older Windows versions as well (such as Windows 95 / 98 / XP).

    During the installation, the installer will ask for an installation directory. The default installation path is set to Program Files (x86)\Microsoft Games of the main drive. On modern Windows, UAC virtualization may interfere with folder read/write permissions, which may cause issues when running the game that is installed inside the protected directory (such as the Program Files above). Therefore, it is recommended to install the game into an unprotected directory (see the Troubleshooting section).

    After the installation process is successfully finished, launch ua_trial.exe file from the main game folder, or via the automatically-created Urban Assault Trial shortcut on the desktop to start the game.

    For uninstalling the demo version, launch UNINSTAL.exe file that is located inside the main game (Urban Assault Trial) folder.

    5.2 Linux

    The official Urban Assault Trial installer and the game software are only available in Windows API by default. However, alternatives such as Wine can be used. The OpenUA package variant of the demo is also available on our website.

    6 Troubleshooting

    Please check the Game Troubleshooting (Windows) article. The majority of the methods described in the linked article also apply to the demo version as well. Alternatively, open a support ticket on the forums to receive direct technical support and assistance for Urban Assault Trial.

    7 Trivia

    • The official Microsoft description of Urban Assault Trial states it contains 6 single-player levels. However, this is not the case in the final public release of the demo version, where there are total 5 single-player levels included. Although it does include a new multiplayer level, named 'Anarchy' (which is based on the single-player level 'Sturmfront'), which is distinct from the multiplayer level with the same name in the Metropolis Dawn Expansion Pack.
    • In the final demo campaign level 'Sturmfront', there is a large urban area comprised of numerous skyscrapers in the north-western parts of the map. The layout of these skyscraper sectors forms two alphabets, 'SK', when viewed on the map or the briefing satellite image. This is a hidden Easter Egg/reference from one of the leading level designers of the game - Stefan 'Opti/Metzel Hetzel' Karau. A similar city layout can be also found in the Debug level.
