Editing Guide to the Supermatter (section)

=== General hints ===
*'''You can break the APC of the room to stop all pipes and scrubbers from working.'''
*Disable the telecomms APC with the CE console to prevent the supermatter from announcing its status.
*Cut cameras near the engine.
*Instead of turning off pumps and filters, you can just set them to extremely low values instead. They'll still appear to be working.
*Taking out all the engineers before attempting a delamination helps a lot.
*Opening a canister of plasma in engineering and igniting it will make it a lot harder for people to fix your sabotage. Even more effective if the radiation levels are high.
*Keep a flash or EMP on hand. The AI and its borgs are pretty much guaranteed to try and intervene to prevent harm.
*Stay around and pretend to be helping so you can undo all the repair attempts by other people.
