Upgrades increase the production of colonies, provide various multipliers to BPS, BPC, and unlock new game features.
Upgrades icon.png
Other ways of unlocking new features and boosting production include:


Bacteria Upgrades

Bacteria upgrades give various multipliers to global BPS, BPC, as well as increase the production of different colonies.

Most upgrades can only be bought once, but some are iterative. Iterative upgrades usually become available after the player has bought 200 of one colony type. Afterwards, they can be purchased once per 25 new colonies.

The player unlocks new bacteria upgrades by purchasing more colonies. After purchase, Bacteria upgrades cannot be sold or disabled.

The Buy all upgrades option is unlocked after the player has destroyed Lableilara.

All bacteria upgrades are lost when attacking a planet or entering a Black Hole.

BPC Upgrades

Iterative BPC Upgrades

Iterative BPC upgrades can be purchased multiple times. Currently there is only one type of iterative BPC upgrade.

It is unlocked after obtaining 100 Bacteria guns and it can be purchased again after each 250 new Bacteria guns.

Icon Name Effect Prerequisite Price (Bacteria)

Regular BPC Upgrades

Regular BPC upgrades can be purchased only once per planet attack.

Gene Strand Upgrades

Gene Strand upgrades enable and increase the idle BPS bonus, tapping combo bonus, as well as provide various multipliers to total BPC and increase the production of different colonies.

New Gene Strand upgrades are unlocked by destroying planets. Previously purchased upgrades can be sold for 2/3 of their original Price (Gene Strands), rounded down.

Gene Strand upgrades remain after planet attacks, but are lost upon entering a Black Hole.
