Grapple is a novice agility skill that allows the player to counter enemies attacks. When a infected or human lunges at you, press A and choose the direction you wish to throw them, you can throw them left right or behind you. Grapple can be upgraded with the Brutal Grapple skill, with this skill enemies that are thrown will fall down. Grappling a infected or human into spikes, ledges and other traps will lead to a easy kill. Grappling an infected into the wall with the Brutal Grapple upgrade can break the targets skull or neck, killing them or stunning them.
