Tips & TricksEdit
Engaging in close combat is the best way to go, as the very high damage coupled with equally high agility will make you a fast-moving killer able to subdue opponents in a few seconds. The increase in range allows you to shoot further away, but the accuracy has no change from Dual Pistols, meaning long range combat with this weapon is not advised. It is preferable to use smaller maps where it is easier to attack from mid-range.
