Github has announced the release of Github for Unity, allowing Unity game developers to better integrate Git and GitHub into their workflow, even if they're versioning large binary assets.
The extension integrates Git and GitHub directly into the Unity Editor with a dedicated window. It includes Git LFS v2.0 support to store large binary assets and introduces file locking so your team knows that you are working on difficult-to-merge files.
