Before I start anything I'd like to say that I'm one of the biggest fans of Twinsanity and I would like to thank Traveler's Tales for creating such epic game as this. The game itself has a lot of pontential to be one of the best in series if they didn't removed half of their ideas. It sucks they didn't had time to finish the game, it could have been the best non-Naughty Dog released game ever.

  Story

Note: This game's story continues where The Wrath of Cortex left off.

Three years have passed since Crash Bandicoot last defeated Dr. Cortex, who managed to escape with his master Uka Uka by landing on a frozen Antarctic wasteland. As fate would have it, both ended up frozen and drifting away through the seas, eventually arriving to the warm waters of their home archipelago. After Cortex defrosts, he decides to get rid of the bandicoot by himself, once and for all.

Later in N. Sanity Island, Crash's sister Coco plays happily near their house. What she's unaware of is that Cortex spies nearby with his little eye. He sets his ray-gun to 'stun' and zaps Coco with it. She becomes unable to move, and Cortex begins the next step of his ingenious plan.
Crash is somewhere at the beach, digging holes in the sand and acting as carefree as he used to three years ago. He suddenly hears a voice calling him. It is none other than Cortex, cleverly disguised as Coco. He tricks Crash into following him to the other side of the bay. When they arrive, Cortex removes the disguise and reveals himself to Crash. Confused, Crash has no choice but to battle Cortex. All of this is just another day in their lives, but little did they know that things were about to take a wild turn.
After a series of mishaps, they are confronted by a pair of weird bird-like creatures. They call themselves The Evil Twins, and they're out to get Cortex and destroy the islands. After showing their surreal powers to Cortex, he runs off faster than Papu Papu to a boar barbecue.
Who are these new enemies? And what business do they have with Cortex? Cortex seeks the answer to these questions, and because he's so terrified of the Twins, he decides to ask Crash for help. Never one to hold a grudge, Crash accepts to help Cortex, if it means getting rid of the Twins and saving his island home. An unlikely alliance is forged, and both bandicoot and evil scientist aim for the same goal, cooperating reluctantly.
