I’m looking for a 3rd person controller on the asset store that is similar to what you get on games like Skyrim, Fallout and Hitman. Are there any like that? I know about the default unity 3rd person controller but that’s not the sort of thing I need. I need something where the mouse, rotating on a pivot round the player’s position, aims a cross-hair and then when you press W (forward) he starts moving towards the target and if you press S (backwards) he starts moving away from that target. I guess if it doesn’t on the asset store I’ll have to make it myself. I just don’t want to go and make something that has been made 10,000 times before.
I’m interested in this too, especially if it works with mecanim 
It has been done 10000 times before. There are a few on the asset store. I cannot say which ones are better. I have some stuff there, they where originally not meant to be character controllers, but they are evolving in that direction. They also do some other cool stuff. Click a few links in my signature and have a look.
