Black Hole
After the player has destroyed a certain number of planets, it becomes possible to enter a Black Hole.
Doing so resets most of the upgrades and resources, but earns the player Dark Matter and can unlock additional features, such as the Dark Matter Institute, where new technologies can be researched.
Black Hole Formation
It takes 25 planets for a Black Hole to finish forming the first time. This number is increased by 2 planets for each Black Hole the player has entered previously.
It becomes possible to enter a Black Hole when its formation has reached 100%. This percentage cannot be exceeded and will remain the same even if the player keeps destroying new planets without entering the Black Hole.
Black Hole Reset
Entering a Black Hole resets:
- Gene Strand and colony upgrades
- Colony irradiation levels
- Destroyed planets
Black Hole does not reset:
- Achievements
- Premium upgrades
- Dark Matter Institute technologies
Resources that will be lost:
- Bacteria
- Nanobots
- Gene Strands
- Bacteria colonies
- Most of the Evolved and Mutated Bacteria
Resources that won't be lost:
- Diamonds
- Dark Matter
- Scientists
Evolved Bacteria have a default 10% chance to survive a Black Hole. This can be increased through Bacteria Irradiation. Before entering a Black Hole, the player will also be prompted to secure up to two Evolved Bacteria that will definitely survive. Only Evolved Bacteria of Level 2 and above can be secured.
Drops
Entering a Black Hole will grant Dark Matter, which can be spent in the Dark Matter Institute.
The amount of Dark Matter depends on how many Gene Strands a player has.
Gene Strands that have been spent on upgrades do not count towards how much Dark Matter is earned.
A player who has reached planet 25 can at most receive 390 units of Dark Matter.
Dark Matter Institute
The Dark Matter Institute is unlocked after the first Black Hole. In the Dark Matter Institute, the player can purchase various technologies.
With the exception of Premium upgrades, these are the only upgrades that are never lost or reset.
Other Features
A feature that is otherwise inaccessible to players is bacteria irradiation, which is unlocked when the 5th planet after the first Black Hole has been destroyed.
Entering a Black Hole also changes parts of planet descriptions.
