SuS: Super Submarine

In Super Submarine, you must captain a humble submarine solo to spearhead an invasion into dangerous enemy waters. Navigate through a maelstrom of endless mines and torpedoes and destroy enemy ships from below. Destroy as many ships as you can, taking care not to run into the plethora of mines that approach you.
While the game is basic in principle, SUS has a unique control scheme that allows for comfortable precision but requires the coordination of both thumbs. By mastering the controls the submarine becomes very responsive and through coordinating you can simultaneously keep your sub alive and deal out some damage. A friendly motorboat may approach and drop you a gear to fully heal your damaged submarine as well.
