How to use DOTS pen?

[Mr. Cakes]

I'm not grasping on what I am looking for with it, or how to use it? Can it be placed by a video camera and be viewed from the truck? I need help figuring this out.

You can do the training to get an idea to what to look for. Basically it is still the ghost as like before, but this time it is just the actual ghost being shown. And yeah, you can still place it (or as of now throw it in a way, that it shines into the room, until they add the option to properly place it like a video cam).

Though given that the ghost will roam to a player in the DOTS state, if there is one to roam to, it is most effective to stay in the ghost room with the dots pen in your hand. It is still possible to see it from a cam, but if there is no player, then it will just keep roaming like before and just might not run through the pens light cone, if you're unlucky (especially in bigger rooms).

So, if I understand correctly, the pen now reveals the ghost itself, instead of creating a little runny boi periodically when the ghost is in the same room. This means that the most reliable way to use the DOTS pen is to carry it, because there are ghost interactions that make it want to be around you.

There is the one ghost type whose DOTS shadow is only visible on camera, so having a video cam at the same time is also good.

This doesn;t mean the old method of monitoring the cam feed in the truck is impossible, just less reliable than before.
