Valve is continuing its efforts to expand its initiative in transforming Steam to be not only a storefront for developers and publishers, but also a place for community-driven content. Recently, the digital distribution service added a Steam Guides section under the Community tab, allowing gamers to submit guides for games they've been playing.
For gamers who need to check up on a walkthrough on GameFAQs (and find the Steam browser clumsy for browsing the Internet) need not ALT + TAB any longer. Steam Guides are easily accessible in the Steam overlay. Guides are broken down into helpful categories, which can be used as filters when using the search bar. Unfortunately, Steam Guide's filtering ability is still fairly primitive, as users cannot filter for language.
Since Steam Guides is still relatively new, there are only a few guides, even for the most popular of games. Still, that's bound to change with time and an improvement in filtering options.
