PlacementPlus for Core Keeper is a mod designed to enhance the gameplay experience by expanding placement options for items in the game. This mod allows players to place seeds, walls, and tiles in organized grids and lines, maximizing efficiency in building and landscaping. With customizable grid sizes ranging from 2x2 to 7x7, along with various placement modes and tools, it provides a more streamlined approach to managing in-game resources.

Key features include adjustable block placement behavior, a color-changing paint brush, and grid-based digging capabilities, all accessible through rebindable key controls. While some features may be missing in the current version, the developer plans to reimplement them over time. This mod is specifically for Windows users and is free to use, but it is important to note that it may not function correctly on Xbox Game Pass.
