Dead Space 2 Message Board  

In Dead Space 2, the Peng Treasure can be found in Chapter 7. After using Watchman Phillips' corpse to unlock the door in his office and navigating three successive corridors to come upon the mainframe room, there are two chambers you must enter to defeat the mainframe's lockout. In the left chamber right next to the access hatch the player comes out of (entering the left chamber) there is another diagram showing the player how to arrange the various circuits, different from the diagram to unlock the lockout. When you arrange the circuits shown on the diagram they will turn blue instead of green. Upon completion another reroute button will become exposed. Use that button to rotate the access hatch to enter the back room.

There lies the Peng Treasure, and two Power Nodes (one in the wall container and another in the green crate on the floor). On rare occasions there will be 3 Power Nodes, the first two previously mentioned as well as a third one on the floor. Collecting the Peng Treasure will award the player with the Achievement/Trophy 'Collect Peng'. It can be sold for 10,000 Credits.
