Power armor, genetic modification-this is the Astartes

[Academy of Sciences report: Genetic enhancement]

[We learned from countless previous failures. Several years after this project began, we officially started recruiting volunteers from the public. Of course, the initial, dangerous modification experiments used death-row prisoners from the Generator District. Later, we began recruiting volunteers from society for safe modifications.]

[Abandon the old body and bid farewell to the past. We removed most useless and recessive genes, dividing the process into two stages-oral reagents and surgical modification-to comprehensively transform an individual.]

[First, after our reagent was administered, the subject's genes underwent massive disruption. This allowed them to break through their genetic limitations and begin growing further, reaching a maximum height of five meters.]

[Next, we used their bodily tissues to cultivate new, thoroughly genetically modified organs, then surgically implanted them into the subject's enormous body so that such a massive physique could keep functioning.]

[Two enhanced hearts and three pairs of lungs were the optimal solution according to our calculations. We also removed the subject's digestive system, replacing that entire collection of digestive organs with highly efficient energy-supply machinery implanted into the abdomen. The inspiration for this organ came from the Plant People. Genetically modified individuals could power their entire bodies by injecting a specially formulated nutrient solution into the abdominal machinery. This was far more advanced than the outdated process of eating, digesting, and obtaining energy.]
