As the name suggests, this game either involves Scando "Barbie Girl" popsters or, more likely, the sea. Aqua is set in the future where a bunch of Anarchists have nicked a satellite that has done something strange to the ocean floor, releasing the Old Ones, big creatures intent on spoiling everything for us humans. As the mercenary Emerald 'Dead-Eye' Flint, you're the only one who can save humanity etc, etc. Anyway, the plot doesn't really matter because Aqua has loads of missions and (judging by the screen grabs) some of the best, most original settings we've seen. Sod depth charges and British destroyers - the enemies of submariners in Aqua are giant squids, sharks and dirty great monsters - far more glamorous and scary opponents.
