Unity

Unity is a video game development platform that's gone from being the preferred option for indie developers (owing to its ease of use and low cost) growing into the industry powerhouse it is today for everyone from indie devs to major studios like Obsidian and InXile.

Unity's versatility lets its users easily create any genre of video game. It also provides the option to work with both 3D and 2D engines. You'll benefit from Direct3D and OpenGL technology -- or opt out of that, depending on your needs. The sky's the limit thanks to this platform, perfect for launching your next video game.

In fact, the most recent version of Unity is compatible with DirectX 11, which allows you to create games with truly spectacular graphics. And, what's more, you can launch these games directly in a browser thanks to one of the plug-ins included inside the engine.

The free version of Unity, which is available on Uptodown, includes the basic tools: a physics engine powered by NVIDIA PhysX, 3D audio, multiplayer capability, and dozens of other options at all levels.

Some well-known games that use Unity include, for example, Triple Town, Bad Piggies, Slender: The Arrival, Dead Trigger, Temple Run, Game of Thrones: Seven Kingdoms, and Wasteland 2.

Unity is one of most versatile video game development platforms out there. And the proof of that is in the enormous number of projects that come out every day for both Windows, Mac, Android and iOS.
