Leviathan: Warships, a turn based naval combat game, was released last week on PC via Steam. This week a tablet version is now available on both Android and iPad for the price of $4.99. All of the versions support cross platform play so you'll be able to pick up and play with just about anybody at anytime. The entire game can be played in co-op and it also offers a handful of co-op challenge maps to play. You can even utilize cloud save and start on one device and finish the game on another - nautical!
