If you want a better look at the map, go to the Safe House. This is almost a screenshot of the desk and map found there. The only difference is they added money piles, cake, the characters, and part of the desk is missing. Most everything else seen is just as it is in the Safe House.

Because of the achievement for using the GL40 on this level, this is often the first thing people try. Every wall possible has most likely already been shot at. Multiple times. If there is a wall that needs to be destroyed, there needs to be some other trigger involved to unlock it first.

Discussions of some strange pathing by the taxman is being discussed in the large ARG thread.

He did not stay there forever. After several restarts I got next results: he stays there and turns to face only when a limo is stuck roughly around the third floor. If limo falls to the balcony, or if a limo is on the roof without breaking it, the taxman does not stop there at all. And last option: if the car is stuck around the first floor, the taxman stops there, but does not turn to face the wall. Most likely it's just a different paths of movement. But still, I'll show you path that seemed to me strange.

Conspiracy time. I am not totally convinced that the purpose of the second static image which points to Bolivia has been found. I am wondering if it is supposed to be for the secret of Undercover. One static image for each secret. I started looking around Counterfeit again and noticed the map on the table with the compass pointing to Bolivia like where the coordinates are. I also notice it has an abnormally large image of a compass on the map which looks like the same design as the rug compass. Could there be any relation between the compass on the map and the rug?

I looked around from the rug in the direction the compass on the map points to Bolivia to see if there was anything interesting. It points to a half table against the wall with two stripped chairs next to it and a boat picture above it. There could be something farther but I would need another person to help.

From what I hear this has been tried a lot during the first ARG. Only the randomized walls can be destroyed, meaning once all the walls are destroyed, the layout of the hallways ends up the same. The police and C4 can also destroy those same walls.

There may still be a chance that explosives are involved in the secret though.

I have read that entire thing multiple times before. Not even a mention of the stairs picture that I can see. I just want to make sure I am not suggesting stuff that was already done before.

Wish I knew all the stuff that was tested during the original ARG, but has anyone done stuff with the pictures of the stairs? Like have the players stand in front of the four normal ones at the same time and see if a sound plays or something happens to the flipped one.

Are all the missions from Payday 1 listed on boxes in the Safe House? I only saw 4: FWB, Counterfeit, Undercover, and Green Bridge. I may have missed some, but if that is all them maybe they are saying Green Bridge has a clue to Undercover somehow.

Also the bright motel sign on Undercover stands out too much for me. I could just be a funny thing they threw in, but who knows. The only clue I could see it representing thiough is that whatever secret there is will only work when the computers are on the bottom floor.

All four pictures from above the laptop in the Safe House can be found in Counterfeit. The stairwell picture is taken from the right stairs on Undercover and from what I saw can be found five places on Cuunterfeit with one of those pictures being upside down.
