01 / STRUCTURE
Bodies and joints
Adjacent blocks weld into rigid bodies. Hinges, sliders, and springs create articulated assemblies with visible body partitions, bounds, and inertia axes.
GAME SYSTEMS // ENGINEERING SANDBOX
The machine
is your answer.
Every contract is an engineering problem with a physical destination. Build the vehicle, wire its systems, load the cargo, and operate it through the same simulated world that tested your design.
BUILD WORKSPACE
Fabricate from first principles.
Enter an owned engineering base to work on an isolated grid with a free-fly camera, configurable part hotbars, and live diagnostics. The editor shows the things that matter before a machine leaves the bench.
02 / SYSTEMS
Pipe and wire
Route fuel, air, exhaust, coolant, rotational power, and typed logic. Engines only produce torque when their complete supporting system works.
03 / DIAGNOSTICS
Read the machine
Inspect centre of gravity, centre of buoyancy, mass, moments of inertia, physical ports, build bounds, and system validity before spawning.
PHYSICAL VEHICLES
Land, sea, and air share one model.
There are no magic vehicle classes. Parts act on the rigid body that owns them, and the environment applies the same forces whether your design looks conventional or completely improvised.
LAND
Contact is mechanical
Wheels are powered tire contacts, not built-in steering or suspension. Geometry, joints, power delivery, and weight distribution are yours to solve.
SEA
Hull integrity matters
Sealed compartments displace water. Impacts can breach them, flooding changes mass and inertia, and moving waves apply buoyancy and quadratic drag per body.
AIR
Forces, not presets
Propellers, rotors, wings, and control surfaces use published fluid-force equations and require actual shaft power or wired control inputs.
Engineering principle: the game re-derives physics from the authored blueprint. Saves contain textual part IDs, placements, rotations, and logic links—not cached performance shortcuts.
CONTRACT LOOP
Build for the work.
The board is a rotating market of jobs with real coordinates, cargo compatibility, access difficulty, deadlines, and transparent reward calculations.
CONTRACT BOARD
Cargo has requirements
Liquids need fluid ports. Loose bulk needs a hopper or open reservoir. Unit loads require enough enclosed volume. Payload immediately affects mass, CoG, and inertia.

DELIVERY
Arrival is physical
A payout happens only when tagged cargo reaches its destination. Lateness reduces the value instead of invalidating the work, leaving room for recovery and redesign.
