"T[size=75]HIS IS THE BENCHMARK STUNT...[/size]"
To hit more then one oppenent gives a negative modification equals to the number of opponents you want to take down. It doesn't matter how you do it, if you shoot down a flag pole over your opponents, if you spend one bullet per opponent, if you throw in a granade or shoot at those highly-exploding barrels - the more opponents you want to include in your attack, the higher is the modification.
How you do it is up to you to describe after the roll.
O[size=75]FFENCE IS YOUR BEST DEFENCE[/size]
Instead of doing a active dogde (+3 on AV), you can parry and try to do a counter attack. It will cost you one shot, but if your opponent fails to hit you, you succeeded with your counterattack. Your damage is your weapons damage + your opponents negative Outcome. In addition, you get to describe the act.
NOTE: The players are here to use their best butt-kicking shoes. This manouver is often used against mooks.
K[size=75]EEP IT COOL[/size]
You can prolong your action with one shot to do +1 damage. Yes, you can use this with "Offence is your best defence". Just remember to describe in what way you prolonge your action. It can be things like saying "KA-CHINK" while reloading an imaginary shotgun, stand in a cool pose, put on your sun glasses, twitch your neck with a loud "crack", slowly pointing your gun against your target, cocking your gun with a loud "click", pulling a one-liner or letting the wind play with your hair or long coat.
Everything isn't about fighting - it's also about intimidation.
I[size=75]T SAYS "CLICK"[/size]
Despite of the heading, you never reload. You always reload when the "camera is filming someone else". Instead, you can sometimes use empty clips as an excuse why the attack didn't work. Imagine Trinity in Matrix saying "Dodge this!" (prolonged action) and pulling the trigger at point blank. It wouldn't feel right if that shot missed, instead it could say "click".
In addition, you can reload by your own by using "Keep it cool" and describe how you in slow-mo is changing ammo clip or perhaps slamming the clip in the weapon with a loud sound.
NOTE: I was tired of the endless pain of keeping track of ammunition.
M[size=75]OVE YOUR ASS[/size]
When it comes to movement, you can find the same way of thinking as in "It says click". You can always move from one place to another when the camera has it's focus on someone else. You can even move mooks in this kind of way, if it's a part of an attack.
M[size=75]OOKS AND INITIATIVE[/size]
They only act on shot 10 and 5 and they are always act before anyone else that are on the same shot. For example, if someone rolls 14 in initiative, then that person may act two times (on shot 14 and 11) before the mooks can act. On the other hand, if someone rolls 10 then the mooks gets to act before that player.
M[size=75]OOKS AND NUMBERS[/size]
All mooks are treated as one opponent when they attack. If there are two mooks attacking one PC, then they get +2 on the roll, if there are three, then +3 and so on. The usual thing is that a horde of mooks attack several PC's at once, so for example eight mooks (gives +8 on the roll) can attack perhaps 3 PC's, rendering "only" (8 - 3 =) +5 on their only roll.
NOTE: Even though I roll 20 results before the session with a home-made dice generator, so I can use 1d20 to roll for mooks, I hate rolling those dices. Why? Because 10-15% of the times, the roll really matters. Now, mooks are more fearsome and the dice rolling is quicker.
