Tidal Tempest is one of those required Sonic levels - the umderwater level. You slow right down in the water and stay under for two long you drown. Sort of half techno and half acient is the theme here but the sound track is very hypnotic.

Very techno would best describe the bad future. Electronic doors and platforms as well as all the water make the level feel like a giant water filtering system. Very pumping sound track.

In the past most of the level is constructed with stones although the influx of technolgy is noticeable.

A good outcome resembles something you may see at Ocean World. Robotnik only needs one hit to finish him. Have enough air bubbles to expose him, avoid a projectile and bang.
