The Volley Attack is a maneuver common to cinema and real life. It represents a multitude of characters all attacking the same target at once, combining their attacks to deal more damage than any could by themselves. (And, though it’s called a Volley, it applies to any situation in which multiple attackers are assaulting a single target.)
Volley Attacks are a special use of the Coordination Challenge rules. Because it deals with both Skill and Combat Challenges, it is slightly more complicated than regular Coordination, though the basic rule is unchanged.
The primary skill in a Volley Attack is whichever combat skill rolls highest, no matter what it is. Related skills include any other skills the gamemaster agrees are relevant. (A manuever, for example, might cause the target to turn, exposing a weak spot.)
All characters generate Skill Totals. The highest combat Skill Total becomes the base Total. Every other Skill Total adds +1 to this base Total.
As this is an attack, the Damage Rating of the weapon used by the highest combat Skill Total is added to the final Skill Total. This is compared to the Defense Rating of the target, with the Result Rating read as Wounds.
Example: A group of characters breaking into a lab are attacked by a security robot. After a couple of futile rounds of attack, it becomes clear that individually, none of them can meaningfully damage the robot. So they volley their fire.
One shoots with a gun (firearms total 13), one throws a grenade (thrown weapons total 12), and another uses a trick to lead the robot off, exposing a weak spot (trick total 20).
The highest combat Skill Total is a 13. This becomes the base Skill Total. Both of the other skill totals beat a 0 DR, so Coordinate. Each adds a +1 to the firearms Skill Total, for a final Skill Total of 15 (13 + 1 + 1).
To this 15, the firearms player adds his pistol damage of 16, for an Attack Total of 31. This Attack Total of 31 is compared to the robot’s Defense Rating. (Had the character throwing grenades rolled higher, his total would be the base Total, and he would add his grenade damage of 18 to the final Skill Total).
Using this method, characters can work together to bring down a single, tough target with coordinated attacks.
