Trap Tower is the fourth level in SegaSonic the Hedgehog.
Upon entering the tower, Eggman unleashes large metal gear-like cylinders to chase the heroes down corridors filled with electrical obstacles, spike traps that will slam down on the floor at regular intervals, and crates that release Rings once broken. One of the cylinders will crash into a pool of oil, causing a flaming torch to ignite the oil, forcing the player to climb up a wall that's dotted with proximity bombs. After that, the exit lies ahead.
In the Revision A prototype of the game, this level appears as the second playable level. It also featured pop-up barriers with Eggman's image on them, and ended with an elevator sequence to the next level, Landslide Limbo.
