This is an exciting time for Call of Duty: Modern Warfare gamers. On Tuesday, a bunch of new game modes were added, and a teaser trailer was released by the developer Infinity Ward. And today, another element has been added to the game! \n \nHere is a promotional tweet from the official Call of Duty Twitter: \n \nhttps:\/\/twitter.com\/CallofDuty\/status\/1225147199362760704 \n \nUntil February 11th, Modern Warfare gamers will enjoy double the experience points (XP), double the tier XP, and double the weapon XP. The reason these benefits have been added to the game is that the first season of Modern Warfare's Battle Pass is scheduled to end on before the 11th, and Season 2 will then begin. \n \nThis is the last chance for gamers to grind matches and gain experience points before season one ends, and now it will be a lot quicker. \n \nBesides having the ability to double their XP, players can enjoy a multitude of different game modes this week. Infinity Ward added the limited-time game mode Face Off Grind. Face Off Grind is a hybrid of two other game modes, Kill Confirmed and Hardpoint, and it features teams of two. \n \nGamers play on a smaller map like Gulag Showers or Shipment, and they face-off against another pair. Whenever a player is killed, they drop a dog tag, just like Kill Confirmed. To score points, players need to pick up the opposing team's dog tags and drop them into one of the objective circles on the map. Gamers can also deny tags, like in Kill Confirmed, by picking up their own or their teammate's tags. \n \nShoot House 24\/7 was also added as a game mode this week. Shoot House is one of the most popular maps in the game, and gamers can queue into this mode to play it nonstop. Shipment 24\/7 was added last week, and it's still available as well. \n \nThere is also a new hardcore mode players can check out in the Quick Play Filter. Modern Warfare gamers can now queue into HC Shoot House and Shipment to play these maps in Hardcore mode. The developer also added Hardcore 10 vs. 10 Mosh Pit into Quick Play. Gamers can play this mode and enjoy a "mosh pit" of different Hardcore game modes, including Team Deathmatch, Headquarters, Domination, and Kill Confirmed. \n \nModern Warfare gamers can play all of these new game modes while earning double XP, double tier XP, and double weapon XP. It's a great time to be a Modern Warfare gamer.
