Cyber Track is much like Techno Base, being a digital-themed level. Like Egg Utopia, it also has gravity shifts that occur by themselves. These are often indicated by arrows on the "wall" pointing up or down. Like many other levels in Sonic Advance 3, this level is abundant with bottomless pits which makes the highest route often the safest, though it is possible to fall off the top of the screen due to the reversed gravity.
Other gimmicks to encounter in this Zone include Flywheels and cannons that catapult the player across a course, like the ones seen in Cosmic Angel Zone. There are also moving platforms everywhere; some travel along set paths, and some disintegrate when stood on. This Zone also brings back a few gimmicks from previous Zones, such as the giant clackers from Toy Kingdom and the rail platform rides from Ocean Base.
Cyber Track Act 3 ends with another fight with G-merl, who utilizes all of his previous moves plus a new shield technique that initially guards him from the player's attacks and the ability to dash across the screen and release a wave of homing missiles. If Sonic is in the lead when Act 3 is finished, Cream will appear, claiming to have gotten lost, and be unlocked for the player to use in the main game and Time Attack.
Dr. Eggman and G-merl are in a machine with a large pipe coming out of the top of it. The characters are on a platform above Eggman, who fires blue energy balls at the heroes. The player must jump into the balls and turn them an orange color and hit them off the walls in such a way that they can hit Eggman. As the battle progresses, Eggman fires the balls faster. After a few seconds of your standing on the platforms on the sides, they'll suddenly drop, resulting in an instant death. After being hit eight times (six in easy mode) with the orange balls, Eggman will escape with a damaged G-merl.
