Unity Technologies is working on adding the ability to simplify 2D game creation using its cross-platform development tools.
A deal between Sony and Unity should also make development of PS4 and PS Vita games cheaper.
Unity Technologies has announced the release of Unity 2.0, a new version of the Mac-native game and 3D simulation engine. It's available for download for free as a 30-day trial; licenses start at $199. Upgrades from 1.x cost $99.
