This is my first time asking a question. I have only ever played D&D and I am now looking for a very different type of system.
My goal is to have a realistic system to use for a Zombie one-shot. I have looked AFMBE but I want a very different combat. (Based on looking at the introductory game kit). I would like a wound system so that if someone has damage to the leg it will hurt their ability to run. I have already seen the previous suggestions for systems that are similar to that but I haven't seen one where you are aiming at a specific location and if you miss that spot you might hit a different location.
Example: You are fighting a zombie and swing at their head with a baseball bat. If you miss you might swing high into the air. However, if you swing low you might hit them in the chest, which would help push a zombie back but not help kill it.
I am willing to alter or combine systems to try and get what I want. However, I haven't seen anything to allow for a miss to have the possibility to hit a nearby location. Does this exist or will I have to make it up?
