You are Catherine Dubont. The Laser Drill opened a cavern 10 miles beyond the surface of the earth. They installed an elevator which you and some others took to go down all the way into the world of the unknown. As you almost reached the bottom of the drill hole, the elevator rope broke and the cabin dropped down the last 100 feet. Everyone is dead. All lights are gone. The only thing you have left is your modern sonar scanner.
Demo of SONAR containing the first level of the game.
To install the demo, just double click on the "SONAR demo setup.exe" and follow the instructions. The self extracting archive will extract the actual installation and run the setup.exe for you automatically afterwards.
The routine may install .NET 3.5 as well as XNA 3.0 to your system, which may take some time until completion.
After this is done and the demo is installed, the demo is started automatically.
SONAR uses a fixed resolution of 800x600 pixels which may be interesting so some of you having some strange sort of display device.
It was tested on Windows XP SP3, but should work on every Windows above that, too. If there is any trouble getting it started, please contact me or just comment it in the download section.
Oh, I almost forgot:
As announced in the news: the first one who comments on this upload in the comment section of the upload itself gets a free copy of the finished game! Good luck!
