Doctor Who: The Sunken Vessel

River warned him but he didn't listen, and now Rory has done so too. When the TARDIS materialises underwater, not doing an environment check spells disaster for the Doctor, Amy and Rory.
The ship’s insides aren't waterproof and don’t take kindly to submersion, especially when a horde of ravenous creatures are sucked through the doors. With the TARDIS malfunctioning and venomous screechers in the water, the trio will have to battle their way through the ship and escape a hail of perils if they are to save their sunken vessel.
