The player can attack every planet an unlimited number of times until it is finally destroyed. A planet counts as destroyed if its remaining population has been reduced to 0. However, it's not possible to attack a planet if the player cannot gain even 1 [[Gene Strands|Gene Strand]] or if he has less than 1 [[Resources#Bacteria|Bacteria]].

If the player has already unlocked [[Minerals]], completely destroying a planet also has a chance to obtain a [[Minerals|Mineral]] native to the current planet.
