Biomass is a tech progression system that serves two functions: increase all lifeforms' maximum Health pool and enable unlocked lifeform abilities after research from the Hive. Each Hive can contain up to 4 Biomass levels; 1 level for being an active Hive and 3 (15/20/40) additional levels can be upgraded by the Alien Commander.
The Biomass progression bar contains slots that will light up to show the current Biomass level, and shows the corresponding ability underneath each slot. It is always visible to the Alien Commander, but is only visible to players when they access the Mini-map, Evolve Menu or check the Research menu (defaultIf a Hive is destroyed, the additional health provided to all lifeforms and abilities enabled by its Biomass levels will be lost. Lifeforms existing before the Hive is destroyed will retain their unlocked abilities, but new lifeforms will not possess them; maximum health pool will decrease according to the current Biomass level. When Biomass levels are regained by building and upgrading a new Hive, maximum health pool will increase again and researched abilities for new lifeforms will be unlocked.
