  • ZMax Xonix Game - classic "Xonix" for Windows PC

    Gaming applications
    The classic Xonix game is a remake, the first version of which appeared in 1984. At the time the game had a huge success. Given the possibilities of old cars, it is not surprising. Although this is not the most important thing. Despite all its primitivity and the absence of three-dimensional graphics, it is still playing in it now. I am also not an exception. Once a long time ago, finding a web version of the game and spending not one hour on it, I wanted to create my own version. It seems that I’ve even started doing something, but it didn’t happen until the release, now I don’t remember why. In the last few days, the game came to me again. This time it was the original of 1984, for the launch of which it was necessary to install the emulator DOC. That, in general, didn’t stop me. Once again killed a few hours, I decided to realize the old idea and make my own version.
