To find it, you must go to the ss anubis and climb the boxes you climbed to find the PLasma Shotgun. then, climb the baxes behind it and go in the door on the upper level. Continue through the depository of the ss anubis, enter the room with your ship, rescue all or all of the tribals you can find, because some are hidden in the darkness of the room for a total of nine tribals, enter your ship and you will be whisked away to the peak walkway. Walk up to the building, destroy all of the soldier drones guarding the area, and enter, inside is a trapdoor that leads to two tribals and a crapload of shield wielding soldier drones. don't go down there just yet. also in the room is a diamond gezzer station, and located in the corner are the Homing missles!
