Amazon’s releasing their very own game engine. Lumberyard, as they call it, is based on Crytek’s famous CryEngine, and can be used to develop games for both PC and consoles.

It’s particularly noteworthy that the engine is completely free. If you look at its competitors, like UnityUnreal Engine 4, or even CryEngine itself, for example, all of them come with either a license fee or a royalty fee.

Lumberyard, which is currently in beta, can be downloaded here.
