What is it?: Reduction in its price and/or start with it free.
As it stands, the game currently can lock you out of Xenobiology and biomass for one simple reason. A lack of low tier bodies preventing you from unlocking a Lazer scalpel.
Marines, IO and pilots often prioritise tier 3 xenomorph corpses, often ignoring the lower tiers completely.
Be it dragging to the fob
Fultoning it
Or choosing which ones to Fulton and which ones inevitably get dropped.
Currently, unless you have a handful of low tier xenomorph bodies, you cannot generate any biomass at all due to higher tier xenomorphs being artificially restricted due to not having a Lazer scalpel.
Unlikely nearly any other department, biomass (much like research credits) have no passive gain, not even extremely slowly.
This more often than not results in situations where researchers stood around, locked out of a specific path of research, despite the fact they could theoretically have piles of xenomorph corpses. But as they are, ironically, the one everyone but researchers may think to prioritise, it can cause weird scenarios as mentioned.
One other side effect is, it also makes research hesitant to spend any biomass because the Lazer Scalpel is so critical. Meaning that “botany” upgrades which lessen the blow of the negative impact of “botany hell” on player QoL.
This could also be addressed by a passive slow biomass system but is less complicated than variable changes.
