Bouncing Betty x2 is a Tier 1 perk in Call of Duty: World at War. This perk gives a player two pressure-activated anti-personnel mines that are planted in the ground. The mines are activated when an enemy player comes in close proximity to the mines; the mine will 'bounce' up and detonate, killing or at the very least damaging any enemy players around it. Bouncing Betty mines have a 360 degree blast radius (unlike the Claymore mines of Call of Duty 4: Modern Warfare). A planted Bouncing Betty has a glowing three-pronged pressure fuse on the top of the exposed part of the mine.
