YouTube is packed full of how-to and walk-through videos. Before you buy that expensive stategy guide, try searching for the information you require on YouTube. Type in the exact question you have. For example: "Where are the hidden eggs in Limbo?" Which, by the way, is available for download via Xbox Live for 1200 points. If that search does not work, or if you want to widen your search just type in "Limbo gameplay" YouTube will provide you with a wide variety of viewing options.
