Steam operator Valve has expanded the storefront of its digital distribution service once again, this time to include strategy guides from Prima. While pickings are currently slim, expect the selection to grow from here on out. Offerings include guides for Dragon Age: Origins, Just Cause 2, Left 4 Dead 2, Splinter Cell: Conviction, and Battlefield: Bad Company 2. The guides can be viewed straight from within the Steam overlay itself, meaning you can bring them up while in-game.

Additionally, in celebration of the launch of Prima-published guides on Steam, Valve is offering the set of initial guides at 50 percent off, bringing each down to $9.99 for a limited time only.
