Well, that was a pretty good game. Here are some instructions. Go to the outside and ask the guy up front for a Russian translating book. Go to the deck outside and talk to the Russian girl. She'll tell you how to make a sandwich. It's one slice of meat, one slice of cheese, one slice of meat, one slice of cheese, one slice of meat and sauce on top.
Go upstairs and give the sandwich to the guy on the left. Go through the door in the middle. Get the plunger and make sure not to step on any chips. That's as far as I got. I don't want to spoil it any further.
