Instructions inside the game.
THE STORY: The most devastating weapon of all has been formed: a power nuke. Placed strategically, it would only take eight of them to completely wipe out all life on earth, no exceptions. Currently only two of them have been created, but when there was an accident with a power nuke, one moment Antarctica, next moment no Antarctica. The other power nuke was stored in with many other powerful weapons in the Nukor. Once news leaked, the Nukor was attacked more than ever before. Your mission: don't let the SRUAMs (Synthetic Robotic Underwater Animal Minions) accomplish their mission: to get the power nuke, replicate it, and destroy the world entirely. (Also the moon would fly off and become and asteroid.)
