Deuterium Tank
Reserve for fleet windows.
What it does
Raises the deuterium cap for fuel reserves and advanced research.
Deuterium tanks secure fuel for travel, research and late-game technology. Without reserves, major operations become fragile.
What it enables
Prepares large fleet launches, expeditions and late-game technology costs.
Cost for level 1
Building time depends on the planet’s Robotics Factory and Nanite Factory levels and on the universe speed, so it is not a fixed number.
Cost per level
Each level multiplies the previous cost by ×2, so each further level gets steadily more expensive the further you push it.
| To level | Metal | Crystal | Deuterium |
|---|---|---|---|
| 1 | 1,000 | 1,000 | 0 |
| 2 | 2,000 | 2,000 | 0 |
| 5 | 16,000 | 16,000 | 0 |
| 10 | 512,000 | 512,000 | 0 |
| 15 | 16,384,000 | 16,384,000 | 0 |
Requirements
None — available from the start, with no research or building gate.
How each race builds it
The four races share the same building rules but not the same hardware — each one names and renders it differently, and applies its own combat multipliers from its race profile.
