Previously beating Halo 3 as the top Xbox Live online game played, Infinity Ward's Call of Duty 4: Modern Warfare's multiplayer still stands on a pedestal above the rest of the FPS titles currently out. And Bungie's not afraid to admit that their Halo franchise "has a lot to learn" from Call of Duty 4's success.

"[Infinity Ward] did a hell of a job with their set pieces, of scripting certain moments that they were really sure the player was going to actually see and experience first hand," said by Bungie lead programmer Damian Isla.

Since its release last November, Call of Duty 4 has been offering an engaging multiplayer experience from the customizable player classes, achievable ranks and weapon arsenal rewards. "[Call of Duty 4] did some very innovative things to keep people going and their experience-rewards system was something that we paid a lot of attention to," said Isla. Athough Halo 3 did have a ranking system, it was mainly for bragging rights, as no rewards were given out (except for pwnage satisfaction). What would you like to see Bungie implement on the game's multiplayer mode (or even future installments)?
