Once you are able to move leave the debriefing room and head towards your marker you will enter some trench's. This path is straight forward with its bends of course but you get the drift. You will follow this around till you get to a giant open area with pulse mines everywhere. You must hit the switch found in the building towards your marker. Once hit head towards the factory and the door will be blown open and your able to walk in. Talk to the general and if you have good speech you can convince him to kill himself and if not then you will have to fight him. Once done you will talk to someone and the simulation will end. Once out head straight towards the locked door. Use the terminal next to it to open and once you walk in the last achievement is yours.
