“System Requirements” means the technical requirements, including the listed supported hardware and software, for Unity Pro as set forth in the documentation for Unity Pro, which is regularly updated for each major release.

“Unity Dependencies” means the standalone software or packages to which Unity Pro is linked or is a dependent executable, and which are not included as part of the core Unity Pro product.

“Unity Source Code” means the human readable source code for the core Unity product that Unity makes available, including any source code contained in Unity-controlled repositories for which Unity authorizes your access, and excluding any sublicensed third party proprietary Third Party Software.
