Strategy, those shots are of from the regular Halo 3.
ssj, CoD4 mimics the Halo 2/3 matchmaking and party system. Bungie revolutionized the way matches are made and rankings are handled, and how groups of people can play together. I may be wrong but I don't recall any game before Halo 2 having a party/matchmaking system. Mainly due to the fact that this is much much easier to implement on a peer to peer system.
