Metroid Prime continues to feed and grow ever larger in the impact crater caves. Its hunger knows no bounds, and it has begun to manifest unusual mutations since its breach. These include armor plating on its epidermis and mechanical outgrowths that generate defense screens. These screens render it invulnerable to most weapon systems, but a flaw in the mutation leads to increased vulnerability to certain weapons. It compensates for this by shifting the screens quickly. This latest development concerns Security units greatly: they feel it's a matter of time before Metroid Prime corrects this defect and renders itself invulnerable to all weaponry. Containment would be nigh impossible if this were to occur.
