Paradox Interactive, a publisher of games and an all-around ship-shape bunch, today announced that Leviathan: Warships, a strategic turn-based cross-platform game developed by Pieces Interactive, has left drydock and is officially launched. Available today on PC and Mac platforms, Leviathan: Warships is a single-player and multi-player game that challenges amateur admirals everywhere to guide a customized fleet of ships to victory in strategic battles. Leviathan: Warships is on sail for $9.99 on PC and Mac, with a single purchase allowing players to play on both platforms. The iPad and Android tablet versions will be available on May 2 2013 and are $4.99 each. All four ports (and starboards) can play together in multi-player co-op and versus modes.
