Scientific Upgrades

If no science can be researched using science points, you will automatically get upgrade points that can be used to gain global upgrades. The upgrade point tier is based on the science tier.

You can exchange 3 points of current tier for 1 point of the next tier using this button.

The science upgrades from tier VI are unique, they give very powerful bonus and have no level of upgrade. Research 3 science upgrades from tier VI to achieve Scientific Victory. Tier VI points may be obtained only by exchanging 3 tier V points for 1 tier VI point.
