The official website announced:
Anyone can now download a full version of the best All-In-One Game Development Engine, for free and use it without charge for non-commercial game development. You can try out the fastest toolset for creating game worlds and use the power of CryENGINE 3 in your own games
I could not test it because it requires hardware requirements.
The minimum hardware resources are:
• CPU: Intel Core 2 Duo 2GHz, AMD Athlon 64 X2 2GHz or better (a multi-core processor is strongly recommended)
• Memory: 1 GB RAM (2 GB recommended)
• Video Card: nVidia 8800GT 512MB RAM, ATI 3850HD 512MB RAM or better (SM 3.0 minimum)
Bellow is a video, also you can find on internet.
