I would also want to know how one would go about learning how to do actually do shit. Do I play challange mode until my fingers bleed or what?
I'm trying to sub him, but having been VERY dedicated to my character, I haven't really bothered trying to -learn- anyone else. That said I can play others, but I don't want to. Carl's the guy, I just need to know where to start.
If you don't play on stick than don't learn Carl.
He can't be done properly on controller and pad.
If you do have a stick I would suggest Challenge mode to learn some combos.
Also spend a lot of time experimenting in training mode.
