Turok 3 Small Storm Texture
After the cutscene that plays after defeating the Oblivion Gunship, you briefly see yourself in 1st person view being warped to the next level. Manipulating the game to avoid being warped, you are able to see the arena has a small texture floating above the arena. This same texture is actually part of the cyclone storm seen above the building at the beginning of the level, only that is colored white and this is colored blue. No idea why this is here, might have been the original sky for the boss arena, but perhaps the developers changed their minds.
