2.5 D beat em up

I want to make a beat em up game similar to Dragon’s Crown using Unity. I’m very new to this so can someone direct me to places that can help me learn how to do this?

Check this forum thread or just google for unity specific resources, there are so many blogs and youtube channels etc to learn from… pick your favorite method of learning.
You can also check the documentation here: Unity - Manual: Unity User Manual 2021.3 (LTS)

PS: Unity Answers is for specific problems, this would be a topic for the forum and has actually already been discussed more than once.
