is there a ep 1 walkthough
Before asking for a walkthrough, you should check the OP. When there's a walkthrough, you'll generally find it there, as is the case with this game.
In fact, as a general rule, anytime you have a question about the game, you should run a search on the thread, to see if the question has already been answered. If you don't find your answer, then post your question.
You don't have to follow these recommendations, of course, but not doing so makes you look lazy, and is just generally annoying for people who regularly follow the thread.
