Rate of Fire
Like in Black Crusade, semi-automatic and full-automatic fire no longer accrue bonuses, but instead take penalties. A single shot also receives a bonus.
Single Shot: +10 to BS.
Semi-Auto Burst: +0 to BS, additional hit for every two additional Degrees of Success.
Full-Auto Burst: -10 to BS, one hit for every Degree of Success.
These actions are also now half actions.
Rules for Overwatch and Suppressing fire remain the same as per Dark Heresy rules.
