Kill aliens under water.

Hint: Strategy game from the 90s

A janitor is persuaded/forced by his boss to become a superhero and thwart an invasion, with some help from the boss' pet.

After your homeworld got crushed, you're one of the last survivors who sets off to find a new home but through time travel gets engulfed in past battles to save the world he left in the first place. It's an RTS where one of the main resources is water, which was released in the late 90's.
