Progression runs on three tracks. Tiers are eras of technology: Primitive, Copper, Iron, Steel, Electronics, Quantum, Planetary, Stellar. Milestones are the story-gated leaps between them. Research nodes are the granular unlocks inside each era. Click any node below and the whole prerequisite chain lights up, so you can see exactly what it takes to reach the Dyson Sphere from where you stand.
Milestones gate the tiers. Each one demands a specific delivery from your factory, and unlocks the next era's recipe set when you ship.
Deliver wood ×40 and fiber ×20. Bootstrap your first crafting bench and basic tool kit.
Deliver copper ingot ×10. Smelt your first metal and the Copper Age opens.
Deliver iron plate ×20, copper wire ×30. Iron, gears, and the assembler come online.
Deliver steel ingot ×40, motor ×8. Foundries, refineries, and chemistry online.
Deliver circuit board ×20, plastic ×30. Electronics, automation, and drone logistics.
Deliver fusion cell ×6, quantum chip ×4. Quantum machines & fusion power.
Grow the Dyson swarm until it sustains 10 PW (10¹⁶ W), the Kardashev Type-1 boundary. Cross it and the Stellar tier unlocks.
Eight tier-stars, seven milestone bridges. Hover any tier to trace its dependency chain. The graph reads from the bottom-left (T0 · Primitive) up and right to the top (T7 · Stellar).
Hand-crafted from the ground up. Wood, fiber, stone. Build a Crafting Bench and a Hand-held Mining Laser. No power required, yet.
Research nodes unlock recipes, machines, and entire industries. Cost is paid in items delivered to a Research Console; duration is real-time progress.
Categorized across Exploration, Production, Construction, Research, Mastery, and Secret. Rarities span Common to Legendary. Every achievement has a unique ARIA voice line that fires when you unlock it.
The research tree is open from the start. Pick a focus (speed, automation, megastructures) and watch your factory specialize.
