## What it is
The Unity Input System is an official Unity package providing a flexible, configurable system for handling input devices and game actions. It replaces the legacy UnityEngine.Input API with support for gamepads, keyboard, mouse, touch, VR/XR devices, custom devices, and runtime rebinding.

## Use cases
- handle gamepad and keyboard input in a Unity game
- support local multiplayer with different input devices
- add runtime control rebinding UI to my game
- create custom input devices for Unity
- drive UI navigation with a gamepad cursor
- set up on-screen touch controls for mobile games
- read VR and XR controller input in Unity

## When to choose
- building a Unity game that needs flexible input handling across multiple device types
- you need runtime rebinding, local multiplayer, or custom device support
- you want an action-based input workflow instead of polling UnityEngine.Input

## When to avoid
- working outside the Unity engine
- your project targets very old Unity versions before 2019 LTS
- you only need trivial keyboard input and prefer the legacy Input API
