Sandopolis Zone is the third Zone of Sonic & Knuckles (and the ninth of Sonic the Hedgehog 3 & Knuckles). It is an extremely large desert with several pits of quicksand.
The first act takes place outside, in a sweltering desert area patrolled by Sandworms, Skorps and Rock'n Badniks. Little sand-falls should allow Sonic or Knuckles to progress up them by jumping, while others will automatically be run up. The loops here are different, because when the player goes through one, they circle for a few moments before being launched high into the air. Upon reaching the end of the act, a pyramid rises out of the ground and a Guardian (resembling the Egg Golem from Sonic Adventure 2) emerges to fight the player. The Guardian can easily be broken apart by a Spin Attack to the head, but will quickly reform and continue to attack. To defeat it, the player must lead it to the quicksand pit on the far left of the area and have it jump in. After beating this mini-boss, the player enters the pyramid.
The second act takes place inside the pyramid. Chains hanging from the ceiling throughout the level act as light switches, and the lights must be on or ghosts will appear to attack the player. Switches can be pushed to open doors to subsequent rooms, although they close after a short amount of time so the player must pass through them quickly. Some rooms have bricks sealed in the walls that release sand flows when broken, which raises the ground level in the room, allowing progression to higher floors but also causing a risk of crushing the player against the roof if they're not fast enough to keep up with the overflow.
