You has just been teleported here from Arrival. The first terminal is a message from Leela explaining that the spaceport on the colony has been destroyed and that the Pfhor are more interested in the UESC Marathon than in the colony itself.She then tells you to find the MA-75 Assault Rifle/Grenade Launcher and to go to another terminal in the area to be teleported out.
When you reaches this terminal, Leela says the Marathon's defenses are down, and teleports you to Never Burn Money to replace three of the ship's circuits and reactivate its defenses.
Obtain the MA-75 Assault Rifle/Grenade Launcher, then find the exit terminal.
Level 29-b Section 10 Public Access Terminal<102.21.521.146>
In this terminal Leela informs you of the destruction of the planetside spaceport and the medium-range radio antennae by the Pfhor. She then directs you to the MA-75 Assault Rifle/Grenade Launcher and exit terminal, while hinting at the behaviour changes in Durandal.
Public Access Terminal 2362-d<12.53.2111.42>
This terminal contains the "unauthrorised access" tags which suggest a S'pht Compiler has been in the system - and indeed, there is one in the room containing this terminal. A "Marathon Internal Engineering Document" is open, describing the different kinds of doors in the Marathon, as well as Durandal's control of them.
Public Access Terminal <101.532.74.95>
The final terminal in the level mentions electromagnetic weapons were used to disable the Marathon's automated defenses and damage the three AIs on board. It also describes the roles of these AIs. Finally, Leela sets up the objective for the next few missions: to restore the Marathon's automated defenses.
The song on this level is titled Leela.
