Graviton Technology

Graviton Technology manipulates gravitational fields. Level 1 is all that is required — it unlocks the Deathstar (RIP), the most destructive ship in OGame. It cannot be researched with stored resources; it requires a continuous energy production feed.
Base Stats
| Property | Value |
|---|---|
| Base cost | 0 Metal · 0 Crystal · 0 Deuterium |
| Energy required | 300,000 energy (must come from current production) |
| Cost factor | 3× per level |
| Prerequisites | Research Lab level 12 |
Graviton Technology is the only research in OGame that costs energy instead of resources. You must have at least 300,000 energy available from your buildings (Solar Plants, Fusion Reactors, Solar Satellites) to research level 1.
Energy Requirement by Level
| Level | Energy Required |
|---|---|
| 1 | 300,000 |
| 2 | 900,000 |
| 3 | 2,700,000 |
Research Unlocks
| Level | Unlocks |
|---|---|
| 1 | Deathstar (RIP) |
Tips
Once you have 300,000 energy production, the research costs nothing in resources. Stack up Solar Satellites or max your Fusion Reactor to hit the threshold.
Almost no player needs Graviton Tech beyond level 1. The energy costs grow by 3× per level and there are no further ship unlocks.
Reaching Graviton Technology 1 is a major OGame milestone. It signals you have the infrastructure to support capital ship production.
