Colony Irradiation

Colony irradiation is unlocked after destroying Earth.

Successful irradiation doubles the production of a random colony. Unsuccessful irradiation yields some Bacteria. One colony can be irradiated multiple times.

It is only possible to irradiate colonies that you have purchased at least once before. If every colony has been purchased at least once, then each colony has the same probability of being irradiated.

The irradiation effect is not lost when entering a Black Hole or attacking a planet.

Only one irradiation type can be researched at a time.

Irradiation Effect

Each successful irradiation doubles the production of a random colony.

The effect of colony irradiation is exponential, which means that it can grow very quickly.

For example, a colony with a Level 2 irradiation will have a BPS multiplier of 4, but a Level 5 irradiation will have a multiplier of 32.

Unsuccessful Irradiation

If the irradiation process is unsuccessful, the player will get some free bacteria instead.

The amount earned is determined by the formula:

BPS × RandomMultiplier × ResearchDurationInSeconds

where

RandomMultiplier - a random number between 0.05 and 0.2
