2D Beat-Em-Up Tutorials?

Hi, for starters, I love the Unity community, you guys are great. Secondly, I was looking for a tutorial for a beat-em-up. Something akin to “Golden Axe” or “Streets of Rage”. Seems like I can find platformer tutorials all day, but can’t find a single one on these types of games. That or either I suck at searching. You guys happen to know of any?

I found this on youtube

A fighting game is essentially a basic platformer, and with each attack you add or enable a hitbox to detect collisions, then apply damage and knockback to other players it detects.
