At GDC 2015 today, Unity Technologies showed off the capabilities of its latest game engine, Unity 5. Unity 5, which is now available globally, promises "massively enhanced" graphics capabilities, improved animation and physics, and more improvements. Games built on previous versions of the Unity engine include Kerbal Space Program, Gone Home, Hearthstone: Heroes of WarCraft, and Broforce. The Game Developers Conference is taking place this week in San Francisco, and IGN will be there covering the event.
