Unity Technologies is revolutionizing the game industry with Unity, a free game engine — software you can use to make your own game. Unity has been chosen by over 2 million developers because it provides all the core functionality needed, right out of the box, to develop great games. Using Unity, you can assemble your game from art and assets, add interactivity, and publish your final work to desktop computers, mobile platforms and the web with no charge whatsoever and no strings attached.
With the added functionality of a Unity Pro license available when you and your team want to tackle creating even more ambitious games, and add-on licenses enabling you to better reach players on iOS, Android, other mobile platforms and consoles, you'll quickly discover why Unity is the favorite choice of everyone from students and hobbyists to major game studios.
