The Leviathan is an interesting idea. it has the same skin and room layout as the Basilisk, but it has no shields and no shield power, which means that you have to pay 150 for shields and another few hundred to power it up. instead, the Leviathan has two Burst Laser MKV's, two Hull Repair Drones, and e Human, Engi, and Crystal crew. the point of the Leviathan is to defeat enemies before they carve your ship up with lasers, and the hull repair drones are for making sure that you can recover from difficult fights. it is harder to play than it sounds: i've beaten FTL twice and have not yet with the Leviathan.
Tell me what you think, if i should change anything. Screenshots and download link should be coming in the near future, but i don't have that articular hard drive at hand right now.
