Duke Nukem 3D, Shadow Warrior, ROTT, more 60% on GOG this weekend

GOG.com is running a sale on Apogee games this weekend, knocking several titles down to $2.39 apiece. That includes crude classics like Duke Nukem 3D, Shadow Warrior and Rise of the Triad, as well as great granddaddy shooter, Blake Stone (pictured). You can also nab the original, side-scrolling Duke Nukem games, or the awesome-for-its-time flight game, Terminal Velocity.
