Tekken 6 features bigger stages with more interactivity than its predecessors, such as walls or floors that can be broken to reveal new fighting areas. The character customization feature has been enhanced, and certain items have implications in some aspects of gameplay. A new rage system has been added, giving characters more damage per hit when their vitality is below a certain point. Once activated, a reddish energy aura appears around the character, and their health bar starts to flicker in red. The rage aura can be customized with different colors and effects to appear like fire, electricity, ice, among others. Another gameplay feature added is the bound system. Every character has several moves that, when used on an opponent that is currently midair in a juggle combo, will cause the opponent to be smashed hard into the ground, bouncing them off the floor in a stunned state and leaving them vulnerable to another combo or additional attack. As of the Bloodline Rebellion update, successfully parrying a low attack will also put a character into a bound state.
