Bethesda is rewarding Dishonored owners looking to check out the DLC-bundled "Definitive Edition." Reddit sleuths noted that Dishonored: Definitive Edition is only $20 on the PlayStation Store (down from $40) if you own the game.
And you should own it if you were a PlayStation Plus subscriber on account of the original being a free game in the subscription service back in April. Mine had run out by then, I think, unfortunately. Mostly because I want to play Pac-Man DX.
