Some YouTubers provide a free uncopylocked TDS place as part of a “How to make TDS” series. Check the description for a Roblox model link (safer than external downloads).

Before we dissect the TDS aspect, let's establish a baseline. In Roblox, every game (or "place") has a setting called "Copy Lock." When Copy Lock is (default), no other user can download or clone the game. When it is OFF (uncopylocked), any user with permission to play the game can open it in Roblox Studio and save a local copy.

While the unlicensed redistribution of proprietary assets (models, sounds, GUIs) remains a valid concern for creators, the open availability of logic and architecture is essential for the health of the UGC ecosystem.

Roblox actually provides an in the Toolbox. Type "Tower Defense Kit" or "TD Kit" into the Toolbox search. These are officially uncopylocked templates that are safe, functional, and well-commented.
