I would like some input from other GM's about rapid fire. Can rapid fire be combined with full auto? Rapid fire allows a character to shoot his weapon as a fast action, meaning he can fire twice. But can he use rapid fire and get all the bonuses from full auto fire aswell?
No, you cannot. Rapid fire allows you to do a normally Slow Action (
Shoot Firearm) as if it was a Fast Action, meaning you can
Shoot Firearm with both actions in your round (once as Fast and once as Slow; or technically twice as Fast Actions). The Talent does not convert all ranged attacks into Fast Actions. What you CAN do, however, is open your round with a Fast
Shoot Firearm single-shot action, followed by a separate Slow
Burst of Full Auto action. At least, that's how I read the rules.
