UBI just put out a free downloadable mission for the fleet boat side of the game, "Tokyo Express". You can get it at their site. I wouldn't be surprised if they put out a few missions in an attempt at some goodwill. You can bet they're gonna be putting out another add-on to expand the Uboat aspect of the game. A lot of people have been clammering for an Atlantic Campaign/Missions. If there's money to be made, UBI will go for it. I just hope they throw us fleet boat boys a few bones at the same time.
