Dead Space 2 – Item Schematics Locations

In the Far Left Corner of the Shopping Area you start in for Chapter 2 is a sealed room. Just to be clear, it is dead opposite of where you start the chapter. If you have a spare Power Node, you can use it to open this door. In it you will find a number of goodies which includes the Schematic for Power Nodes
