The PlayStation 4 launches this Friday and SOE has already prepped DC Universe Online (DCUO) with a fully loaded update. Game Update 31 rolled out just a short while ago, adding a new graphical overhaul to the game to prepare for the upcoming PlayStation 4 launch. Along with a set of shiny new graphics, DCUO also received additional leveling content, improved player rewards, and a number of other tweaks and improvements.
DCUO is currently available on the PlayStation 3 and PC. It will also be available on the PlayStation 4 as a free-to-play launch title this Friday.
