Stratus City

Stratus City is a city high above Kortog and under Tachyon's rule. Ratchet and Clank ended up here by being dumped out of a ship by the Smuggler because they were about to get vaporized by a detection that detected a Lombax in his vessel. Is here that Ratchet fights his way through the city to the Hall of Knowledge. It is also where clank gets the Robowings as you can fly anywhere in the city but watch out, you will fall if the triangle button is pressed or if you hit a wall or any flying cars.
