Unity is a special method to implement 3D effects more realistically. We partly use Unity in the game development to make an impressive gaming experience possible. Games based on this technology need a special plugin, the ‘Unity Web Player’, for playing through the browser.
You can download the plugin from the following link: Unity Web Player
Follow the link and click on ‘Download’ on the web page. Once the plugin is downloaded, launch the installation and follow the instructions to complete the operation. Normally the plugin recognises which browser you use and automatically sets up the optimal version for your system.
Please note: Please close all other programs on your computer before you begin with the installation. You may need administrator rights on your PC to install the ‘Unity Web Player’.
