Metro3D has shipped Sub Rebellion as an exclusive for the PlayStation 2.

Developed by Irem Software Engineering, the game takes place in the 22nd Century, after geological imbalances force most of the world's countries into the drink. Players control a futuristic submarine exploring and attacking through about twenty levels of state-of-the-art 3D graphics.

There are ten subs featured in the game, and discovering submerged artifacts reveals ancient technology useful for upgrading the vehicles and their weapons. Searching for ancient civilizations and other treasure provides elements of exploration, but shooting fans (and Sqoon fans) will be glad to hear that Sub Rebellion is a fast-paced shooter at its core.
