Back Off Man. I'm A Scientist Trophy

  • Back Off Man. I'm A Scientist


    Obtain 100% PKE scans for every paranormal creature.

    There are 48 unique ghosts and 4 substances that you need to scan in single player throughout all missions. Press to enable PKE Meter and use to start scanning a ghost you are looking at. You can see a list of everything you have scanned by pressing button and then go to 'Tobin's Spirit Guide'. Note that the 'Sloth Ghost' is added to the Spirit Guide automatically and doesn't need to be scanned.

    When using your PKE Meter you will wear the Ecto Goggles, the environment will become green and you will see three circles on the screen. To get a 100% scan the inner circle needs to be green when you start scanning the ghost. If the middle circle is yellow (50%) or the outer circle is red (0%), then you won't get a full scan. If you don't get a 100% scan it will still show in your Tobin's Spirit Guide. If you look at the information on the scanned ghost you will see that some sections are missing depending on how much you managed to scan, just make sure it doesn't say '-- Unknown --' in the ghost information. All information needs to be available to count for this trophy.

    Use 'Replay Mission' to find the ghosts that you are missing. They don't have to be scanned in one playthrough. You will get cash for every scan so that you can buy upgrades within the game.

    You can see how many ghosts you have scanned in each mission by going to 'Replay Mission' on the main menu. Ghosts that you have only partially scanned won't count towards the total.

    Besides the ghosts you also need to scan 4 substances. They can be found in almost all missions. These can't be seen in 'Replay Mission' but are still required for the trophy. Even if you see that you have scanned all the ghosts you might still need one of these four.

    The substances are:

    • Black Slime (Replay Mission: Hotel Sedgewick / Air in the Lines)
    • Black Slime Portal (Replay Mission: Times Square / Hindenburg: The Musical)

  • The Check List Link no longer exists.. :(
  • Each chapter will tell you what ghost is missing.
  • For some reason the game isn't updating when I scan the venom crawler. No matter how I scan it or how many times I do it after the boss battle is done I check on the next level and I still don't have it registered in the codex.
