The Hub and Sandbox Mode — BoneLab Walkthrough

Exit the Conceptual Isolation Chamber by prying open the doors or escaping through the roof hatch.

Explore the three initial modules as tasked by the bulletin board.

After exploring three modules, energy cores will unlock above them. Progress to the control room.

Pilot the BOSSCLAW using the provided controls (lever for extension/retraction, directional movement, button for magnetic gravity field).

Use the minimap to guide the BOSSCLAW to the unlocked energy cores. Activate the gravity field to attract them.

Bring the attracted energy cores to one of the six flanking tubes. They will snap into place when close enough.

Attach energy cores to any three pipes to unlock the massive quarantine airlock to the right of the control room.

Return to the Hub later in the game to explore the remaining modules and retrieve their cores.

Once all six cores are attached to their pipes, the BONEWORKS door to the right of the control area will be openable.

To access the Hidden Room: Enter the metal vents underneath the lab. Find corridors leading to two walls with hand-drawn doors. Use a keycard found in Stress Level Zero's offices to cross one wall, leading to a room connected to the Lab but physically underneath MythOS City's District 05. The purpose of the second hand-drawn door is unknown.
