Thunder Force III but I can't think of too many that take place within the big blue wobbly stuff entirely. One that apparently does, though, is this much-derided PC Engine exclusive. Despite this setting, there are still aliens involved in the back-story who have reportedly infected our wonderful oceans with evil bacteria which has made the creatures that dwell therein grow larger and follow the commands of their new masters. Earth's only defence against the attack is the A.N.G.E.L. Fish Attack Sub which is, as you might've guessed, a submarine... with the appearance of a fish! Thankfully its abilities exceed those of most marine lifeforms and by using these you, as the sub's anonymous pilot, must eliminate a substantial portion of said lifeforms. Poor fishies :(
RKS Score: 3/10
