A lot of Blackberry users have played Battleship growing up and now it has been adapted to work with your BlackBerry under the name of Sea Battle. This game operates similarly to how the classic does and also incorporates BBM 6 to play with other users across the BBM platform. The only way that you can play this game is if you have OS 6.0 and BBM 6.0. So, if you have you phone loaded with these items feel free to download the game free here.
Thanks to N4BB for bringing this to our attention.
