Evil corporations, experiments nuclear submarines, now we're talking secret agent stories! The Ancient Aquanaut sees our L.A.N.C.E. agents investigating one of the biggest barriers to keeping the world safe. Cornwell Consolidated, corporate evil-doers of the highest order.

Cornwell's new experimental submarine was exploring the deep sea looking for, well we're not quite sure. But they brought something on board. Something they should have left alone. Now it's all gone wrong. L.A.N.C.E. has the black box data, but what truly happened on that sub?

This story can be approached in many ways. As the poor Cornwell employees on the submarine and uncover the truth as it unfolds. Or perhaps as L.A.N.C.E. agents who find the wreckage and whatever still lies within.
