Shockwave is an antiquated technology and is rarely used anymore. In the past, it has been used to create 3D games using Adobe's Director software, which usually provided a .dcr filetype. These games are no longer playable in Chrome, Firefox nor Edge. You may however be able to play them if you use Internet Explorer, and install the requisite plugin. If you can get these games to work, they boast some pretty impressive 3D graphics, often used for racing games. One of the best is City Drifters.
