The Force Gauge is a small blue bar that is beneath the player's HP Gauge in Soulcalibur IV. It is used by The Apprentice, Darth Vader, and Yoda for their attacks that require the use of the Force. It is drained as Force powers are used and slowly replenishes over time and when landing successful hits. Once the Force Gauge is exhausted, the character will be overcome by the Force and enter a state of dizziness, becoming temporarily stunned (Yoda and The Apprentice clutch and shake their heads, while electricity surges through Vader's life-support systems).
