Transcript[edit]
Avoid going through the Central Chamber! Marcus and his goons have started patrolling the area and setting up turrets. Getting caught by them won't end well for you. Please, exit here or further up the tunnels. Pass it on to everyone you can think of. We can't lose anybody else to this senseless violence.
