What would you do when you discover the secret of life, where the beginning where all lifeforms were designed and mass produced, will you stay sane or accept reality? Here in the massive lab you found exactly knowhere and stumbled upon, will you restart its reproduction and design newer lifeforms to develop before its release to the "World" or become a mad scientist that creates beings that would terrify the entire "World" in your journey to godhood? Wait. This place is the origin of life, what is a god? What is a beast, what are creatures? They are a product of this lab.
After some years of studying in the development of the creation of new lifeforms you found out the whole reason why the lab was abandoned. It was not out of fear of birthing a being that can erase or transcend reality, that was one of its purpose, the previous owner's intention was to create a vast variety of living creatures and its duty was completed when the first being capable of reproducing came to existence.
But then you wondered, is the real owner of this abandoned lab truly stopped and halted the progression of certain entities to come to life like silicon based machine lifeforms? Why? Could it be this said owner has no taste in machines? What about the drafts? Are they left alone? What about the previous lifeforms that do not contain the ability to reproduce? Why didn't the lab's owner revise their biology to not handle reproduction and develop lustful tendencies.
No need to worry. Right now with the lab's power creating an army to fight for you and reusing it for later is one of the features you have thought of. Scared that after losing your army they will get shared across the enemy camp? Don't forget to add the function that removes their source of reproduction, changing their sex organ to the reproductive organ of a certain creature on the "World" to rapidly transform its entire tissues and organs to eggs that shall birth zergs that will follow your every command.
Having trouble not having your way into loving these insects? Don't worry, use the lab again to create a new lifeform connected to zergs so that when a higher ranked zerg has a chance of birthing a bipedal humanoid zerg with the body closely resembles that of humans.
After all the lab's purpose was the creation as the origin of life. One design will make the possibility of it appearing in the "World" or locking it so it's only possible to reproduce in the lab.
