This page intends to provide links to *.unitypackage downloads from across the web that are not currently available in the [unity asset store]. When adding links to this page please be sure to organize them under a category that you think you would find it if it was available in the unity asset store. For example if the package contains game scripts include it under a "Scripts" section, if the package contains functionality that extends the unity editor include it under the "Editor Extensions" category etc.
- GeneralTools — Provides a number of general purpose tools & game scripts that assist you in performing general tasks within Unity that you would otherwise not be able to do with just the Unity editor tools alone.
- Script Templates — Helps you to create scripts from custom templates.
