Benefit: When using an automatic firearm with at least five bullets loaded, the character may fire a short burst as a single attack against a single target. The character receives a –4 penalty on the attack roll, but deal +2 dice of damage.
Firing a burst expends five bullets and can only be done if the weapon has five bullets in it.
Normal: Autofire uses ten bullets, targets a 10-foot-by-10-foot area, and can’t be aimed at a specific target. Without this feat, if a character attempts an autofire attack at a specific target, it simply counts as a normal attack and all the extra bullets are wasted.
Special: If the firearm has a three-round burst setting, firing a burst expends three bullets instead of five and can be used if the weapon has only three bullets in it.
