Coming out of left field today, Tim Sweeney posted a new video on the Unreal Engine YouTube channel that announced that Unreal Engine 4 will be available for free for anyone to download. Yes, the engine that is powering some of the upcoming hits for the new consoles and PC can be yours for the low price of free.

Of course, the next question is what sort of catch is attached to this, and there is one small one, but it only comes into play if the programs you develop are commercially successful. Once you register on the Unreal site, you can download the full Unreal Engine 4 suite of tools. You can then make any game, program, virtual reality title you wish and if it sells over $3000 in revenue, you will give 5% of the money earned back to Unreal, hence the registration.

If you are someone just looking to get your feet wet with a new, powerful development tool or someone with a great idea that can’t afford to buy a development engine upfront, Unreal Engine 4 might be your ticket to fortune and fame.
