You may be new to this concept but it turns out that you can punch people

here is how you can

Press LSHIFT (left shift, it's below caps lock)

but what if this isn't as accurate as you want? well if you hold right click on your mouse you can lock on

if you like this like lmk if you want to do it on a controller
this is really difficult and obscure knowledge but i am sure that i could find that out somehow
