One Call of Duty: Modern Warfare 2 player recently shared their own cross-map quad kill that they managed to pull off during a Ranked Search and Destroy match. When it comes to Call of Duty: Modern Warfare 2, players occasionally pull off incredible feats such as a quad kill. Another incredible feat commonly shared online is the "cross-map," when a player uses a grenade or tomahawk to kill an enemy from the opposite side of the arena. While both a quad kill and cross-map are notable in their own right, it's very rare for a player to achieve both at the same time in Call of Duty: Modern Warfare 2.
