O21 is a modern free and open-source remake of U95, a game by NIKITA company, released in 1995.
Some of the game engine features have been implemented, but the game is not in a playable state.
Visit the issue tracker if you want to know more.
Currently, O21 is only suitable for development mode. To start the game, run the following shell command:
$ dotnet run --project O21.Game -- <downloaded-data-directory>U95 (also called as U-95 on the title screen) is a game well known in the 1990's Russian-speaking gaming community, since it was one of the first games published there.
It was created in 1995 by one of the first Russian game development companies, NIKITA (currently renamed to Nikita Online), for Windows 3.x.
Since the original game is probably named after a German submarine U-95, that was sunk by Dutch O 21, the authors decided to name the remake project O21, as a (wishfully) superior project (at least in some aspects).
This section is maintained by me, the O21 project lead, Friedrich von Never. The statements made in first person are all mine, do not hesitate to contact me if you have any comments.
All the content and code in this program (except the O21.Game/Translations folder and the fonts, see below) is covered by the MIT license.
This program is designed to use resources of the U-95 game by NIKITA. This project is not affiliated with or endorsed by NIKITA in any way. The project is non-commercial. The source code is available for free and always will be.
This is a blackbox re-implementation project. The code in this project was written based on reading data files and observing the game running. In some cases, the code was written based on specs available on the Internet.
I believe this puts the project in the clear, legally speaking. If someone disagrees, please reach me.
The distribution license of the original game is unknown, so the game has an unclear de jure status. De facto, it is abandonware nowadays.
No assets from the original game are included in this software (though it may allow the user to use any assets downloaded under the user's informed consent).
This software bundles the Inter font, covered by the SIL Open Font License.
This software also bundles the microGM sound font, published under the WTFPL 2.0 license.
