Ground and Pound, also known as Ground Strike is an ability that is unlocked when Agents reach Level 5
Strength. When an Agent reaches a certain level of height, pressing the "B" button allows the Agent's fist to glow red and smash the ground when he lands on it, creating a large shockwave that throws people and vehicles to different directions. Players can also use any melee weapon to use in a ground and pound.
