Me and hobbit found

We just found third step! Upgrade the Scavenger and shoot the tip of the red beams from the 4 generators through out the map, will video it later 4th step they say they need some Vodka we have yet to find where this is!

Step 1: Turn on the power and go to the room in lighthouse with a generator and a door knife the door a couple of times and the 4 previous characters will talk to you and tell you they need a fuse so they can see.

Step 2: Go upstairs and look on the 2 desks there should now be a flashlight looking object on one of them hold X and you should now have an indacator on the screen that you picked it up

Step 2B: Take it back to the door and hold X and the control panel next to the door and they will start talking again. They will ask you to destroy the power coming from the generators (there are 4 of them they all look the same as the one on the oposite side of the door they will now have red light coming out of the top)

Step 3: Get the scavenger upgrade it and shoot the 4 generator beams with the upgraded scavenger and the lights will go out after all 4 are dark go back to the door knife it and they will begin talking to you and ask to bring them some Vodka.

Step 4: Find the Vodka!
