Steam and Prima have teamed up to free you from the shame of purchasing strategy guides at retail, with a selection of downloadable guides you can launch directly from Steam's UI overlay.
Whether you're having trouble with the final boss battle in Dragon Age: Origins, or you can't figure out where you're being sniped at from in Battlefield: Bad Company 2, Steam and Prima have you covered. The first batch of six in-game Prima guides go up for sale on Steam today, allowing players to download and read at their leisure, or pop them open directly in the Steam overlay, where they can quickly be hidden from view in case you have company.
Each guide costs $19.99, but in celebration of the launch, each is currently half off, or $9.99.
I buy strategy guides myself, mainly because I enjoy having a physical record of the games I've played. That, and they look very nice on my bookshelf. In my case, downloadable strategy guides are a waste, but for others they could be a real lifesaver.
