Space Elevator & Project Assembly

Space Elevator & Project Assembly

The five phases of Project Assembly, the parts each phase needs, the tiers they unlock, and the standard recipe for every Space Elevator part.

Version check pending: The phase-cost and standard-recipe tables are hand-maintained and still need comparison with current schematics and recipes.

The Space Elevator unlocks with Tier 0 – HUB Upgrade 6 and is the second building the game asks you to construct after the HUB. It never produces anything itself; instead, each of its five Project Assembly phases asks for a quantity of one or more parts, delivered by belt or dropped in by hand. A phase completes only when you confirm it manually, so you can stockpile parts and turn several phases in at once.

The five phases

Phase Name Parts required Unlocks
1 Distribution Platform 50 × Smart Plating Tier 3 + 4
2 Construction Dock 1 000 × Smart Plating, 1 000 × Versatile Framework, 100 × Automated Wiring Tier 5 + 6
3 Main Body 2 500 × Versatile Framework, 500 × Modular Engine, 100 × Adaptive Control Unit Tier 7 + 8
4 Propulsion 500 × Assembly Director System, 500 × Magnetic Field Generator, 250 × Thermal Propulsion Rocket, 100 × Nuclear Pasta Tier 9
5 Assembly 1 000 × Nuclear Pasta, 1 000 × Biochemical Sculptor, 256 × AI Expansion Server, 200 × Ballistic Warp Drive Ends the game (Launch), grants the "Employee of the Planet" cup

An Advanced Game Settings cost multiplier (1× by default) can scale every phase's requirement up or down for a new save. After Phase 5's launch sequence, the world keeps running as a sandbox and every tier stays unlocked.

Space Elevator parts (standard recipes)

Every part also has one or more alternate recipes discovered on Hard Drives; the table below is the default recipe only.

Part Building Standard recipe Output/min
Smart Plating Assembler 1 Reinforced Iron Plate + 1 Rotor → 1 (30 s) 2
Versatile Framework Assembler 1 Modular Frame + 12 Steel Beam → 2 (24 s) 5
Automated Wiring Assembler 1 Stator + 20 Cable → 1 (24 s) 2.5
Modular Engine Manufacturer 2 Motor + 15 Rubber + 2 Smart Plating → 1 (60 s) 1
Adaptive Control Unit Manufacturer 5 Automated Wiring + 5 Circuit Board + 1 Heavy Modular Frame + 2 Computer → 1 (60 s) 1
Magnetic Field Generator Assembler 5 Versatile Framework + 2 Electromagnetic Control Rod → 2 (120 s) 1
Assembly Director System Assembler 2 Adaptive Control Unit + 1 Supercomputer → 1 (80 s) 0.75
Thermal Propulsion Rocket Manufacturer 5 Modular Engine + 2 Turbo Motor + 6 Cooling System + 2 Fused Modular Frame → 2 (120 s) 1
Nuclear Pasta Particle Accelerator 200 Copper Powder + 1 Pressure Conversion Cube → 1 (120 s) 0.5
Biochemical Sculptor Blender 1 Assembly Director System + 80 Ficsite Trigon + 20 m³ Water → 4 (120 s) 2
Ballistic Warp Drive Manufacturer 1 Thermal Propulsion Rocket + 5 Singularity Cell + 2 Superposition Oscillator + 40 Dark Matter Crystal → 1 (60 s) 1
AI Expansion Server Quantum Encoder 1 Magnetic Field Generator + 1 Neural-Quantum Processor + 1 Superposition Oscillator + 25 m³ Excited Photonic Matter → 1 (15 s) 4

Nuclear Pasta, Biochemical Sculptor and Ballistic Warp Drive all run in machines with a variable power range of 500–1 500 MW, and AI Expansion Server's Quantum Encoder ranges 0–2 000 MW – budget generator capacity generously before starting phase 4 or 5.

Planning around the phases

Phase 1 (50 Smart Plating) finishes in about 25 minutes from a single Assembler running at 2/min. Phase 2 is the first real jump: at 2/min per Assembler, 1 000 Smart Plating takes roughly 8.3 hours from a single machine, while 1 000 Versatile Framework at 5/min per Assembler takes about 3.3 hours – so most players run 4–8 Smart Plating Assemblers alongside a couple of Versatile Framework lines rather than waiting on one of each. Phase 3's 2 500 Versatile Framework alone is 500 Assembler-minutes at the standard 5/min rate.

Phases 4 and 5 lean on the aluminium, nuclear, particle and quantum production chains introduced from Tier 8 onward; a Somersloop in the final assembler of a chain doubles its output without adding another machine, which matters once individual parts are worth hundreds of thousands of sink points each.
