Okay Paradox, nice job with this trailer. It did its job, as made me pay attention and even write about Leviathan: Warships on Dtoid. Not that we haven't written about it before. In fact our own Fraser Brown went hands-on with the game.
Leviathan: Warships will be out on April 30, 2013 for the PC, Mac, iOS, and Android, and best of all, there's asynchronous cross-platform multiplayer across all devices. You can grab it for $9.99, and purchasing it early will grant you the "Marauders" downloadable content pack for free.
