O21 is a modern free and open-source remake of U95, a game by NIKITA company, released in 1995.
Currently, we are still at the exploration stage; scope of work is to be determined.
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 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).
