After synthesizing the vaccine, you'll need to retrieve the G-Virus sample. Head to the West Area, which is heavily guarded. Navigate through the Bioreactors and the Greenhouse. In the Greenhouse, you'll need to solve a plant-based puzzle to access the Control Room. The solution involves adjusting the chemical dispenser to the correct levels (refer to the notes found in the area). Once inside, you can access the G-Virus sample. Be prepared for a significant boss encounter shortly after acquiring the sample. Ensure your inventory is stocked with healing items and powerful weapons.
