星門引擎
星門可以用於遊戲角色的傳送，但需要電力或合適的資源來解鎖，且角色手上拿的物品會脫落。
Gateway Engines are structures that make up the cores of each planet. They are large, spherical structures, with many pillars extending outward and up through the outer core layer of the planets. The pillars and sphere in the center have their own gravity separate from the gravity of the planet. When approaching any part of the engine, the player will be pulled and oriented to the surface of the structure and will be able to walk "normally" along the surface. As gravity changes, the player will be noted by an acoustic signal, in order to reduce confusion.
As most pillars are not connected to the engine directly, the player will need to jump to be able to attach to the central sphere or build bridges using the Terrain Tool. There are two pillars - that represent the north and south poles - that are directly connected and will easily allow the player to walk onto the outside of the sphere. In the interior of the central sphere, there are three "bridges", the top, and bottom, each of which will orient the player to be able to run along to get around without issue.
When first approaching the Gateway Engine, there may be a forcefield blocking the interior if none of the Gateway Chambers have yet been activated on the surface. Once it is lowered, the player may enter the interior of the sphere. On one side are three raised platforms, similar to the Chambers, that will require a specific resource, marked with a specific symbol on top of each platform. Once the required item is provided, a Geometric Triptych will appear in the middle and the forcefield will raise. The player must take the triptych up one of the three bridges to the opposite platform. There, in the center, is a single platform with a slot for the triptych. Once it is placed, the engine will activate and reveal an Odd Stone, allowing teleporting to chambers on the surface, as well as to the satellite. Additionally, the forcefield will lower once more, allowing the player to leave the engine.
Planets
Each Gateway Engine requires a specific resource to create a Geometric Triptych, which is required to activate the Engine. Only one of the resources is required for each planet. The Geometric Triptych is unique to each planet and can be created repeatedly. Note that two triptychs are required: One to activate the engine, and another one for the satellite.

Trivia
- The Gateway Engines, much like the Gateway Portal satellite, provide oxygen once the player has entered the sphere that begins at the first holographic pattern that surrounds the core structure.
