HQ4Games says: "Enough about the complaints and disappointment, let`s get to the multiplayer review. The multiplayer in MW3 is as expected; there are both core (standard) game types and hardcore (advanced) game types. Under each option there are a number of different game types including the two popular new game types Kill Confirmed and Team Defender. Kill Confirmed “…requires players to collect floating dog tags from the corpse of a downed enemy before the kill can be registered. However, the opposing team can pick up the dog tag as well to deny the other team of a kill.”"
