Seriously! has an announcement from Devolver Digital revealing plans for Serious Sam HD Gold Edition, a four game bundle that will be released via Steam this Thursday. In addition to the HD versions of Serious Sam: First and Second Encounters, the bundle will also offer the original versions of both of these action-packed first-person shooters from Croteam. Serious Sam: The First Encounter and The Second Encounter were both released through GOG.com, so this lends some credence to speculation that tomrrow's planned statement on the uncertain state of GOG.com might be some sort of merger with Steam.
