Unity 6 (6000.0) or later. The free Core on its own also runs on Unity 2022.3 LTS. The systems marked needs a server also talk to a PHP and MySQL backend you own: its requirements and setup are on Server setup.
Bought in the shop
In Unity: Assets → Import Package → Custom Package…. Import the Core first, then the system you bought, then the systems it needs, as your order page lists them. The packages share the same file identities, so nothing is duplicated.
The free packages
The Core and the Extras are free for everyone and need no purchase: download them from the systems page, then Assets → Import Package → Custom Package…, the Core first and the Extras after it.
From the Asset Store
Three listings: the free Core, Platform 2D and the whole toolkit. Add yours to your assets, then in Unity: Window → Package Manager → My Assets, find UGTK, Download and Import.
