Sand Ocean is the third stage in the Dark storyline of Sonic Adventure 2 and the second stage playable with Eggman. It represents Eggman's attempt to return to his Hidden Base hideout, after his confrontation with Knuckles and Rouge.
After returning from Prison Island from where he released Shadow Eggman sets off to his secret base, taking notice that there’s an emerald sign on the area. Since Shadow has asked him to bring Chaos Emeralds the next time they meet, Eggman does a detour and finds Knuckles and Rouge fighting over the Master Emerald, and not a Chaos Emerald like he initially thought. Still, he snags it, thinking he could use it for something, but Knuckles foils his plans by smashing the emerald into pieces. Eggman leaves the scene baffled at the echidna’s antics and continues his way back to his base.
Sand Ocean is desert themed, with an interesting concept of bottomless pit, since the level is constructed above sand where the Egg Walker will sink into immediately if in contact, because the mecha is too heavy to sustain its weight above the surface. Since Sonic is lighter, he'll be able to escape the sand by repetitive jumping, as seen in the Egg Golem boss. It’s Egyptian themed as well, with large murals, hieroglyphs in small square platforms, and giant statues with an Eggman like head on top. For some strange reason, there are flags and gas tanks with the GUN’s insignia emblazed on it.
The major gimmicks of this level are the pillars that can be knocked over by locking-on to the Dynamic packs attacked to the base of it, form new paths and access other platforms and gyratory platforms that make alternative paths easier to access.
Other level specific-objects are torches and fire pots that will hurt if touched, black and yellow jars that can be smashed, GUN gas tanks, that were already mentioned, that can be destroyed and then used to reach higher heights
Eggman first starts in a platform with half walls, similar to Tails’ “houses” but not quite. After this there’s a gyratory platform, which can lead to three ways. The one on the right and past some steel containers is a dead end but contains some rings, the one on the left leads to Eggman’s Mystic Melody upgrade is. There’s a Mystic Melody here as well, which is a massive shortcut to a stone pillar section that will be mentioned below. Back at the gyratory platform and following the forward path, there’s some moving platforms over the sand, another half wall platform and the first stone pillar with dynamite packs that can be knocked off. Using will access a hallway of some sorts and halfway down there’s another stone pillar that can be knocked off and up the staircase there’s a third stone pillar that can be knocked on, that eventually leads to the first Point Marker.
Here there’s a gyratory platform and platforms over the sand, leading to yet another stone pillar that can be knocked off. At the end there’s another gyratory platform has two ways, one beyond and the other to the right where the second Point Marker is. Regardless of it, the forward path leads to some platforms over the sand, which access a larger one beyond them.
Past the Point Marker there’s more square platform, moving and stationary, over the sand and another stone pillar that can be knocked off. A the end there’s a drop down platform and past the staircase and to the right there’s the stone pillar section close to where the Mystic Melody shortcuts to. Past this and a similar setting as the beginning of the level, there’s two GUN gas tanks, which destroyed make a path to another section with more square platforms, moving and stationary, a gyratory platform and the third Point Marker.
At the end of the long platform there’s a jump plate that will launch Eggman to a hallway of some sorts, with various pillars that an be knocked off, making a staircase upwards that Eggman will take to reach the level above, where the Goal is.
Sand Ocean and Tails’ Hidden Base are both in the same area, on the outskirts of the pyramid that is Eggman’s base, so they share the level theme and various objects, with some small variants, though the first is set at night while the latter is during the day. Their gimmicks are also very close to one another as well, with one having a progression path based on knocking down platforms or pillars to proceed forward. Sand Ocean also shares some of its desert and Egyptian themes with Sonic’s Pyramid Cave, the murals or the giant Eggman’s heads, and both Knuckles’ Death Chamber and Rouge’s Egg Quarters, with hieroglyphs and Eggman statues scattered through the level.
