Top-Down 3D Action Game Prototype

I’m building a top-down 3D action game that lets the player switch between two distinct humanoid characters on the fly. Each character will have its own movement set and core ability, so the code has to handle seamless swapping, shared health and inventory, and a camera that never breaks the top-down perspective.

Here’s what I need from you:
• A lightweight Unity (or Unreal, if you prefer) project with basic terrain, lighting and collision in place.
• Two placeholder humanoid rigs, each wired to simple idle, run and attack animations.
• Character-swap logic coded and ready for me to extend.
• A responsive top-down camera that follows smoothly and respects obstacles.
• Clear, well-commented scripts so I can expand the combat and AI later.

Deliver the project folder ready to open, plus a short read-me explaining how you structured the scenes, prefabs and scripts. If everything runs in-engine without errors and I can press one key to switch characters, the job’s done.
