Key takeaways

• Unity now presents the Input System package as the preferred input solution for most projects.
• The older Input Manager remains available for legacy projects, but the documentation frames it as secondary.
• The Input System package is installed through the Package Manager, not treated as part of the old built-in UnityEngine.Input workflow.
• Unity highlights the package’s flexibility and editor-side configuration workflow, especially the Actions editor.

Notable claims

• Unity’s manual says the Input System package provides the engine’s “best support” for input.
• The Input System package is described as more extensible and customisable than the classic UnityEngine.Input approach.
