But Among Us is a 3D game proved here. And also, does GODOT support blend files?
Viewing post in How do you make NPCs in Blender Game Engine?
Among Us is made in Unity.
Godot doesn’t support the .blend format. It can, however, import a few formats that Blender can export to, for creating assets (See the Godot Manual). You won’t get far in a “codeless” engine; Blender Game Engine uses Python, if memory serves correct. Godot does have visual scripting if text scares you, however.
