It's an attack OPTION. You can either make a single-shot attack with a firearms (almost any), a double-tap attack with a firearms with semiautomatic mode, or an autofire attack with a firearms with automatic fire mode.Aesmael said:I am having a little trouble having understanding how autofire works. In particular I am not sure if it is meant to be used as a standard (attack) action or if it can be used in part of the full attack action when the character possesses iterative attacks.
And, if you have the Burst Fire feat, you can make a targeted autofire attack against a single opponent rather than the less accurate hail of bullets into a 10 x 10 area. And, the Strafe feat allows you to change that autofire area to 5 x 20.So, if you're a 6th-level Strong Hero (BAB +6/+1), you can make one autofire attack as an attack action or two autofire attacks as a full-round action.
