Play incredible 3D games from your browser
You've probably know Adobe Flash, which for years has allowed you to see some pretty cool things in your browser, while being an almost constant security threat with far too regular update notifications. The Unity Web Player is a huge leap beyond Flash, allowing for detailed, smooth 3D graphics we're used to seeing only in standalone games. It works with Internet Explorer, Firefox, Chrome, Safari, and Opera.
Unity itself is a tool for developing 3D games on all platforms, and the web player does not mean you can play any Unity developed program from your browser. This extension allows you to view web content created in Unity. There are, however, lots of really impressive games you can play in your browser if you install this.
