I posted about some of this a few pages back, but did not receive any comments. Since we are back on this topic, here is a streamlined version of what I was considering. Any comments from someone who knows the rules better then I (or have actually played the game) would be welcome.
AUTOFIRE
Aiming Autofire is not allowed. Add 1 Difficulty (2?) to the roll if you declare AutoFire. Each Success provides +2 damage instead of just +1 damage. Less chance of hitting, but when you do you get a damage bonus because more bullets hit. Advantages do not cause Criticals, but Suppression instead (see below).
SUPPRESSION
Only automatic weapons can attempt. One Success causes target to be Distracted (loss of Maneuver). Multiple Successes causes target to be Stunned (loss of Action). Each Advantage rolled causes a hit (+1 damage per Advantage). If this is too powerful, add 1 Difficulty unless an AutoFire weapon?
EXAMPLES OF BOTH
AutoFire: Medium range (2 Difficulty) plus AutoFire equals 3Difficulty (if this is not enough add 2?). Only 1 Success is rolled, but it gives +2 damage. One Advantage is also rolled which doesn't give a Critical, but suppresses the target making him Distracted.
Suppression: Three Successes are rolled. The target is Stunned. Two Advantages are also rolled indicating the shooter got lucky and got a hit for +2 damage (as if 2 Successes were rolled) even though he was only trying to suppress the target.
WALKING FIRE
AutoFire weapons could use Walking Fire for either normal attacks or Suppression. You add an extra Difficulty die to either mode for a chance to hit or suppress multiple targets.
