Call of Duty‘s Expo in Los Angeles is officially underway and being streamed live on the Call of Duty Livestream channel. In case you miss it, to kick off Call of Duty XP, a brand new multiplayer trailer for Modern Warfare 3 was premiered, which you can check out below.
The trailer shows off the new Strike Package system that allows players to continue to build killstreaks even after dying in certain objective modes. In addition to the new killstreak system, a new objective mode called “Kill Confirmed” can be seen in the trailer where players must pick up dog tags on the players their team has killed in order to add points to their team’s score and win.
