Headquarters – Call of Duty 4: Modern Warfare
Calling the CoD 4 multiplayer experience ‘intense’ would be an understatement. If you like intense, chaotic multiplayer gameplay, CoD4’s Headquarters is for you. I know most of you are probably too hooked onto Team Deathmatch to even bother with the other modes, but if you don’t play at least one game of Headquarters in every one of your CoD4 multiplayer sessions, consider it incomplete.
Headquarters is completely like the ‘King of the Hill’ mode you’ve seen in other multiplayers like Halo. The way this mode works is that every few seconds a location on the map becomes the ‘Headquarters’. The team that gains control of this location starts stacking up points; the first team to reach the score limit wins. What sets it apart is the awesome gameplay mechanics that go hand-in-hand with this mode. The intensity of the ‘hot-zone’ is multiplied by the airstrikes and choppers that get called in constantly. Add the fact that you have the entire team running around the map constantly while bullets fly in from every corner – and you have a win-win situation!
