Identification and Corrections

• The term "Bio-Bed" may refer to biological samples or specific chambers in the game; the original term is retained here.
• Directions mentioned in steps (e.g., 110 degrees, 278 degrees) are relative bearings based on the entrance of the previous Bio-Bed.
• No. 2 Bio-Bed requires heat resistance, meaning you need equipment such as a heat-resistant knife or upgraded diving suit.
