    2. Activate the terminal and select the Advanced Infiltration Test. Your objective of obtaining the documents from the office’s wall safe will remain the same, but now you must do so without touching a series of laser tripwires scattered about the area.
    3. The safest way to complete this task is to follow the quest marker back into the office and disable each tripwire you come across. Do this by interacting with the black cylinder that each laser beam emits from. You will need a specific amount amount of science or repair points in order to be eligible for this strategy.
    4. If you want to instead maneuver around each beam, move forward after entering the Testing Area and jump onto the reception desk. Walk along the left end and up onto the bookshelf to drop back onto the ground safely.
    5. Move to the back wall and go right through the unguarded doorway. Vault over the last cubicle on your right continue forward through the hallway, weaving between the lasers that point up from the floor.

    9. You have the option of disarming each mine by pressing the button of top of it, but this is often dangerous and the mine’s location is sometimes obscure. A more efficient tactic might be to maneuver around the laser beams in the same manner as before only with consistent speed to avoid detonation.

    12. This test works in much the same way that the Beginner’s test did, only now you will need to sneak up on each of the enemies to disable them. For speed and strategic purposes, it might be best to dis-arm yourself for this challenge.
    13. After you enter the Testing Area, hop onto the furniture as usual and drop to the right of the shelf to disarm the first mine. Now you can move forward and get a line of sight on the open doorway to the right.
    14. When the patrol has turned away from you, move past the doorway and disarm the mine on the table to the left. You can now enter the cubicle room and disarm the mine on the ground to the left of the second desk ahead.
    15. Return to the previous room and make your next available left to navigate around the beams and enter the room of that first patrol.
    16. Crouch down to avoid detection and move up behind the patrol. Press X bring up the option to disable, then move forward towards the next doorway. Get a safe line of sight on the patrol down the hall and move behind the wall ahead when he turns his back to you.

    Field Research

    1. Before beginning this quest you’ll need to have at least started the Old World Blues mission to obtain the key to Forbidden Dome Zone Entrance.
    2. Almost all of the items you need to collect in this quest can be found in places you’ve already traveled to, so there shouldn’t be much trouble locating them. You may have even picked some of them up in previous quests while sweeping a particular room.
    3. Your first two location choices are either Higgs Village or the Forbidden Dome Zone Entrance. Two audio samples can be found in the second story rooms of the houses indicated by your quest marker within Higgs Village. The third is on a table in front of Dr. Mobius’ lab within the X-42 Robo-Ware Facility.
    4. There are now three locations to acquire seed samples which must be taken by defeating spore plants. Pick up the first seed sample on the second floor of the Botanical Garden.
    5. The remaining two locations cannot be discovered, so first travel to the Signal Hills Transmitter. Move right across the fallen tower that bridges the canyon and defeat the nearest spore plant to pick up the second seed sample.
    6. Move north past the nearby fountain and walk across the pipe that bridges the gap. There is a mine laid on this pipe so be sure to disable before crossing.
    7. Eliminate the spore plant to your right and pick up the seed sample in the grassy area ahead. You may now return to the Sink.
    8. Once you are inside the Sink, hand off the audio samples to the juke box and the seed samples to the Biological Research Station to complete the final quest.

    Old World Blues

    1. Travel to the Think Tank and talk Dr. Klein to let him know you’ve completed your tasks. Click through the conversation at your leisure until you are charged with going to the Forbidden Zone Dome Entrance. Some topics of conversation will require a specific number of points in areas such as Repair and Science.
    2. Travel to the Forbidden Zone Dome Entrance and enter the door that leads to the X-42 Robo-Ware Facility. It is now time to face the Giant Scorpion.
    3. As soon as you enter the room , the Giant Scorpion will begin to power-on. Take cover in the room to your right and arm yourself with the Sonic Emitter, as it seems to be the only weapon that will do damage to it. It is also a good idea to take some Rad-X if you have any, since the enemy’s weapon cause severe radiation poisoning.
    4. While inside this room, the Giant Scorpion will power back down. Use the nearby terminal to learn more about its weaknesses and send out drones that will attack it. These drones have no effect on the health of the Giant Scorpion but are to be used as a distraction.
    5. As soon as the drones are deployed, the Giant Scorpion will turn away from you. Use this opportunity to leave your shelter and do as much damage as possible with your Sonic Emitter. If he returns his attention to you, take cover in the one of the surrounding shelters. Take this time to heal yourself before returning to the fight.
    6. Repeat this process until the Giant Scorpion is defeated. You may now follow your quest marker up one of the metal staircases in the corner and enter the building to the right.
    7. Move through the building and out the other side, then enter the door on the left. You can also use this opportunity to pick up the audio sample on the table in front of the door.
    8. Once inside, move up the ramp ahead and talk to Dr. Mobius floating around by the monitors on the ground floor. Click through the conversation, choosing the more polite approaches if possible, to learn all the backstory. If you have enough Repair points you can offer to fix Dr. Mobius’ damaged monitor.
    9. After you have finished the conversation, follow the quest marker to the second floor and approach the brain tank. When your the tank suddenly deploys from the top, talk to your actual brain. You’ll need a specific number of points in Speech, Science and Medicine in order to access some topics.
    10. If you do not have the necessary points, choose the topic about compromise and strike a deal. Your brain will reject this, so return to the original topics and tell him he’s coming with you.
    11. Promise to take better care of yourself to learn about the tools you’ll need for the brain surgery. Decide to take your brain with you on the next objective. You can also decide to leave him in the tank and come get him later.
    12. Achievement / Trophy Unlocked: Make Up Your Mind – Decide what to do with your brain, whether it be to take it with you or leave it alone.
    13. Talk with Dr. Mobius to formulate a plan, then you can either leave peacefully or kill him. If you choose to kill him, he will be gin firing on you and robot scorpions will appear.
    14. Exit the building and return to the outside. You may first want to sweep Dr. Mobius’ lab for supplies in the rooms on the second floor and on the table at the ground floor.
    15. Return to the Think Tank and approach Dr. Klein to talk with him. If you have completed all other quests in this game that deal with his colleagues and have enough skill points, then you should be able to reason with Dr. Klein peacefully.
    16. If you decide to fight, then tell Dr, Klein about the pacification field to start the battle. If you use the Sonic Emitter, it shouldn’t take much time to eliminate Dr. Klein and all of his colleagues. Once they are all defeated, you may exit the Think Tank to complete the quest.
    17. Achievement / Trophy Unlocked: Outsmarted – Complete the Old World Blues quest.
    18. Once the cut scene has ended you will be rewarded with a Transportaponder, which teleports you between the Mojave and the Big MT whenever you pull the trigger in an outside location.

    This walkthrough has been really helpful. Too bad I found out about it during my final two quests. I just wanted to say that I found the Tesla Cannon to be a better weapon against the Giant Scorpion.(That is if you’ve made it to level 45 I guess).

    The Giant Robo Scorpion. Use the Anti-Material rifle with explosive rounds or in one of the shelters there is a code(or just hack, if sci=100) the scorpions self destruct.

    Joel, just use the sonic emitter to blast the force field; it’s what I did. I found the unlock code much later.
