Table usage[edit]

Legend indicators:

Colors: Starter , Acquisition , Rare , Dangerous , Repeatable .
Icons: Armies / Attachments , Buildings , Components , Edicts / Policies , Feature unlock , Starbase, Resources , Ship / Station class .

Notes:

The table shows the default names/icons of techs. Flavor entry is displayed if accompanied by a change to effects/requirements.
If a tech has been available as a research option in the as part of the last choice then its (total) weight will be halved in the coming choice.
The table denotes the base cost of a tech. Actual in-game tech cost will scale with the empire's size (number of colonized planets and population).
To research techs of higher tiers it is first needed to acquire 8 techs of the preceding tier.
Sorting the table by tiers will place all Starter tech at the top and Repeatable end-game tech at the bottom.
Most icons also double as links. For more information about an unlocked effect (buildings, components, etc.) click on the accompanying icon.
