When you’re dealing with a convoluted plot in which scientists want to perform nano-experiments to purify water on a “molecular level” aboard a ship the size of a city that’s about to get taken over by socio-environmental terrorists as it floats in the Indian Ocean; you’d be right to reach for that klaxon marked “bullshit.”

We do know that the terrorists who want to disrupt the experiments follow the teachings of 19th century political economist Thomas Malthus who suggested that the world’s human population would grow faster than the production of food. These Malthusians want less people on the planet - and this new water treatment could give clean water to millions and help create more hungry mouths. Malthus’ projections suggested that we’d start running out of grub midway through the 20th century, but we didn’t and he was proved wrong.

Of course the real reason you play as system engineer Kate Wilson on the floating citadel - called The Queen of the World - and must save scientists obsessed with water by fighting the water-purifying-technology-hating terrorists is because of Blade’s HydroEngine graphical wizardry.
