Location from Resident Evil 4 by Capcom
The island's Plaga research facility — where parasites are cultivated, hosts are tested, and bioweapons like U-3 are assembled.
The research lab is where RE4 reveals its full scope. Las Plagas isn't a natural infection that Saddler stumbled onto — it's a carefully studied, deliberately weaponized organism. The lab contains documentation of Plaga life cycles, host compatibility experiments, and mutation protocols. U-3 was created here. The Plaga injected into Leon and Ashley was cultured here. The lab sections mix combat with environmental storytelling. Tanks contain failed experiments. Surgical rooms show evidence of forced Plaga implantation. The researchers' notes shift from scientific curiosity to religious fervor as Saddler's influence grew. It's the game's most disturbing environment — not because of monsters, but because of the deliberate human choices that created them.
Sterile corridors with fluorescent lighting, specimen tanks filled with Plaga organisms in various growth stages, surgical theaters with restraints, and cold storage units. Computer terminals display research data. Some sections are damaged — containment breaches have left Plaga growths spreading across walls and ceilings. The contrast with the ancient village and Gothic castle is stark: this is modern, clinical horror.
