After kickstarting its first season of content earlier this month on 3rd December, Call of Duty: Modern Warfare is back with a Season One refresh that adds even more classic multiplayer maps to its online offerings. Available to play right now, you can get nostalgic by playing Shipment and Vacant from Call of Duty 4: Modern Warfare for free.

The notoriously tiny Shipment map has been given a British makeover, but it still looks to be just as hectic if the trailer above is anything to go by. Vacant is another fan favourite map which has been brought back from the dead -- ensuring that you're in for a very good time whenever you boot the game up next.

There's even more to this Season One refresh, however. Shipment can also be played in Gunfight and it's joined by a new map named Over Winter. More Special Ops experiences can now be played co-operatively, joined by further limited-time modes. It all seems like more than enough to keep players occupied over the Christmas break.
