Rare Techs: Unlike regular Techs, only one of each Rare Tech is ever available per game. When Researched, Rare Tech Tiles may be placed on any Tech Track on your Species Board and you receive the discount applicable to the chosen track as if it were a regular Tech.

Rare Techs are not allowed to be chosen as a reward for the Ancient Tech Discovery Tile.

Note: Detailed descriptions of each Military, Grid, Nano, and Rare Tech are included in the various Technologies sections.
