One of Dr. Eggman's many chemical plants, the Spaceport is an industrial high-tech maze in the frigid north of Sonic's world that serve to supply a nearby space port. This location was ultimately raided by the Resistance when the group needed a space shuttle.
Like its other incarnations, the Spaceport is an industrial area with no natural environments. Unlike earlier versions of Chemical Plant however, it is presented in a maritime zone, as a kind of industrial platform. Here, gigantic and metallic structures in yellow and gray rise up from the sea and into the sky like skyscrapers. The majority of these structures include high-tech factory-based chemical plants (some of which glow orange) and industrial cranes. Among the structures are various pipes, ducts and containers for transferring and holding blue chemicals. Also winding between the structures are yellow and black-stribed roads, yellow and blue tubes, and train tracks for freight trains transporting supplies.
Further into the stage, it is possible to see that the place also serves as a space port (as implied by its name). At the end of the stage are countless shipping containers that are being transported between the Spaceport and the Death Egg through Eggman Fleet vessels that dot the sky.
Due to being located in the northern region of Sonic's world, most of the Spaceport has frozen over thanks to constant winds and cold weather. Surfaces of ice fill up the base, the buildings are covered in a thin layer of frost, and the air is chilly with falling snow. The stage is also overcast by a clouded sky.
After Dr. Eggman and his Eggman Empire managed to subjugate 99% of the world world, the Resistance has discovered that Sonic the Hedgehog, whom they believed to be dead, is being held prisoner onboard a space station. Having just recruited a rookie soldier, Knuckles sends them along with a squad to the Spaceport to steal a shuttle that the Resistance can use to reach Sonic.
Upon arriving at the Spaceport, the rookie fights through enemy forces while Vector's squad focuses on the task at hand: finding a shuttle. While Espio's team is busy holding off enemy forces however, they notice that Infinite has arrived. Thanks to Espio providing a distraction though, the Resistance is able to get through to the launch pad, where Vector's squad manages to procure a shuttle. The rookie is then order by Knuckles to retreat as soon as everyone has escaped.
Like other Avatar stages, Spaceport features floating targets for the player to swing around on using the Wire Attack, and numerous Wisp Capsules with Wisps for fueling the Avatar's different Wispons. However, any Wisp Capsule containing Wisps that do not match any of the Wispons the player has currently obtained will be rendered intangible and transparent until the player obtains their Wisp's associated Wispon. This means, for example, that if the player does not have an Asteroid Wispon, then the capsules with Indigo Wisps will be unobtainable.
The stage begins with the Avatar running down a metal bridge, whose perspective eventually switches from 3D to the side-scrolling 2.5D perspective. Eventually, the player will pass through a shuttle loop and be launched into the air, before automatically swinging down to a narrow passage with Grind Rails at the end. While grinding along the aforementioned rails, the perspective will switch to 2.5D again.
At the end of the Grind Rails, the player has to scale a series of platforms. At the top, they must then Wire Attack another target to trigger a cutscene sequence. This sequence shows the Avatar landing on a freight train after swinging away, only to be forced to grapple to higher tracks to avoid hitting an approaching tunnel. Up there, the Avatar manages to grapple past another incoming freight train in the last second. After that, the player must complete a Real-Time Interaction; the better the player times the Real-Time Interaction by pressing the jump button when the green rings that appear overlap, the greater the point bonus the player will receive.
After the Real-Time Interaction, the player will land in a long 2.5D section with multiple path options. At the end of this section, the player will return to a 3D perspective as they get catapulted to another Grind Rail segment. After this segment, the player will arrived in the shuttle port, with the goal in front of the stolen space shuttle.
