A group of Call of Duty: Modern Warfare 2 players discover a new movement technique called the G-Walk which not only makes them harder to hit, but increases their speed dramatically. Movement in any multiplayer shooter is an important element, especially for a series like Call of Duty. Traditionally, each game has their own mechanics that players need to adapt to such as the exo suits from Advanced Warfare, when to tactical sprint, and even dive to prone aka dolphin diving which became popular in Black Ops.
