In the beginning of the DLC, you will have to drive Father James to Sammy's...
After a cutscene and a very short shootout, you will be tasked to get your camera from the same room your safe is in....
Next task to to investigate the bar,press
to active your "Intel View", objects outlined in blue need to be investigated, if it's outlined in yellow, you already checked it out.....you will need to examine 3 bodies, an incense holder, a knife (needs to be rotated so you can see the edge, you will see a small white "shining light" when you are in the right position, then press
to "investigate"), a bowl, and a sign written in blood.....
After you are done, leave the bar, step outside.....cheevo pops!!!
