Found something VERY interesting, if you go to the inn where you play darts there is a notice on the board. It reads " I Love 72, Drayon Brain and suring the web BE MY Friend 555-0164" So i called the number and i got an alien sound, try it for yourself guys, weird stuff, i'll post a pic up now.
Edit:- Ok No way of uploading the pic but try it for yourself guys, weird.
Can we get a few things confirmed about the shack?
Firstly do you have to be 100% to see the agents?
Secondly a photograph of the shack itself and also the location on the map?
Yeah I think for now we should focus on the shack, anyone not 100% able to go there and could someone post an image of the location?
The alien noise also happens if you type in any gta 4 cheat
and the shack is here http://prntscr.com/1stn9o

I'm thinking it could just be an entrance outpost to the labs with all the CCTV cameras and FIB agents.
