Shooting and all other combat abilities would work off of skill+Primary Ability=Factor against anothers skill+PA=factor with environment factors added in. Lets say awareness for ranged so a score of 7 and a skill-firearms-chosen weapon .38 revolver of 6 = a 13 VS. agility of 6 and skill of dodge 5 =11 the prime equation would be overwhelmingly in the shooters favor and as such he would hit. Unless the character being hit had decided to use Fate Points(When a character is asked about an action they WILL have to declare using Fate Points before a conclusion is brought about). So lets say that character di dnot use any the target woudl be overwhelmed by 2 points which would equal a Damage Threat of 2. I will get into Damage Threats later on a step at a time here
