Want to build a mobile game? Unity Technologies is now making it possible for anyone to develop games for Android and iOS for free using its platform.

Unity's cross-platform development tools can be used to create games for a multitude of different platforms, including smartphones, PCs and game consoles, simultaneously. This comes as welcoming news to many developers who previously had to fork over $400 each if they wanted to create games for Android and iOS, but that will now be completely free, Unity CEO David Helgason said in a blog post Tuesday.

"Mobile game development has exploded into probably the most compelling part of the industry," Helgason said.

The tools are free for independent developers and small studios. However, "companies and other "incorporated entities" with a turnover in excess of $100,000 in their previous fiscal year are required to use our paid version," Helgason noted.

Of course, there are limitations within these now-free add-ons that will require the Pro version of Unity ($1500) to circumvent, but this will at the very least give you a good idea of what's in store if you wish to port a game.

Unity Technologies said users who already have the program installed, all that needs to be done is update the software to access the Android and iOS build options.
