ND 29: The Silent Spy

Just played my 3rd play through, and this time I got all awards but one, the Treasure Hunter.

Any clue how I can achieve this award?

Treasure Hunter, I believe is getting all the coins in the game.

The problem I had is, I re-search in past places and didn't find any place with available coins

I found 4 in my replay this AM. It does take some seconds for the flashing lights to come on. There might some missed. I believe there is at least one in every location. I have not examined the maintenance room and the "lair" yet.

with the help of the list on http://community.herinteractive.com/showthread.php?t=1297806 I finally got it

I also even found the third easter egg too
