Build a space factory. Mine, harvest, exploit. Manage logistics with railguns, ballistic payloads and gravity-bending haulers. Fight gravity with Focus, climb the tech tree. Expand and explore the solar system in this Newtonian automation sim. Everything is a potential resource - even the Locals.
ASEMA
SteamIn Asema, you build a sprawling industrial empire in a zero-gravity Newtonian sandbox. You start as a single pioneer drone, manually harvesting resources and physically bumping asteroids into your first basic refineries. As you scale, you construct a vast logistical network where conveyor belts don't exist - instead, you manage momentum and placement: physically plugging distributor railguns into your machines, flying heavy haulers to colonize distant moons for more and new resources, and aligning massive railgun arrays to automate the flow of physical payloads across the void. The engine handles the complex orbital physics; your job is to design the ultimate automated machine.
Everything is a potential resource - even the Locals.

Resources in Asema are physical objects with mass. To automate your production chains, you must master the art of space logistics. Build localized grids by physically locking distributor railguns into place. When a local moon runs dry or is not enough, pack a heavy space hauler, manually fly to an icy asteroid stream you discovered earlier while scouting the space, and establish a new beachhead. To connect your distant outposts, build and align automated long range railgun artillery arrays on moons to fire glowing resource payloads safely across the darkness.

Operating near celestial bodies introduces a unique environmental puzzle: gravity. Your heavy machines will naturally drift toward the nearest gravity wells, such as moons. In Asema, anything can become a gravity well when it has enough mass - even one of your own machines. You don't need to calculate orbital math or plot trajectories: you just need to manage your economy. Build and power dedicated Focus arrays (computational anti-gravity) to keep your grid stable, counter the pull of the moons and gravity wells and keep your factories perfectly positioned.



Climb a vast, branching technology tree to discover increasingly exotic ways to manipulate matter. Expand your operations from the deep gravity well of the inner solar system out into the freezing, distant reach of the Void. Exploit the Locals, balance the thermal output of your arrays, and fulfill your cosmic destiny.
You are old, one of many. There may be an infinite amount of your kind in the cosmos, older than stellar dust. But for you, the only space that matters is the one you can silence.
