Compared to your previous battles, this last one is a breeze: just two
cyborgs and a medium robot. Blast the door, dispose of the guards, head
east into the next room, then climb over the middle cabinet against the
north wall to the ladder. Just keep climbing up to Level 4 and go north
through the force fields to the Master Robot Recall Console. Talk to it and
enter the three deactivation codes. Don't make a mistake or you'll go
straight to SRC!

Primary code: CHLOBU
Secondary code: PERABR
Tertiary code: EDDONE

Now, just sit back and watch the action, read the epilogue, and receive
your congratulations. The fireworks will continue until you reboot.

Briefly, the frontal assault proceeds as follows:

Slaughter robots. Take the up transport tube on each level until you get
to Level 2 (third floor). Use the Jetpack to go against the conveyor belt
flow, then west to the up ladder, and all the way up to Level 4. Go north
to the terminal and input the codes. Explore Level 3 and Level 4 via the
transport tubes if you wish; there are down tubes. You cannot reach the
terminal from the room on Level 4. The door is blocked by trash and that
room has an ARMY of robots!
