1. Starting area: look through the window at green-marked tubes labeled A–D. Read BACD order on the pad (B=3, A=9, C=5, D=2) and enter 3952 on the first door keypad.
2. Dr. James Holt / Halt zone: find the ID paper in a cabinet (password 63F8C74). Enter it on the computer to unlock the authorized section.
3. Chemistry room: fill five test tubes from the periodic-table poster—atomic 82 Lead (green), 37 Rubidium/Rb (red), Helium from the balloon (pink), 79 Gold (yellow), Oxygen from the H₂O clue (blue). Collect the red button from the opened cabinet.
4. Plant room: press the hidden button under the table to run sprinklers, then replicate the flower color pattern on the empty plot using the red button slot.
5. Key + control room: grab the shutter key, enter the control room, and set Water 4, Food 2, Oxygen 27%, Temperature 75 (window gauges + table paper). Take the screwdriver, open the vent above the shutter-key box, and crawl out to escape.
