DC Universe Online's Last Laugh DLC pack for a while now. Fortunately for fans of diabolical supervillains everywhere, launch day is finally here. The pack represents the largest PvP content update since DCUO's release, and it also puts the Joker on center stage as the key figure in a "criminally twisted new storyline."
If that's not enough to whet your whistle, Last Laugh also features new shield powers, safe house battles, headquarters battles, and legends characters including Power Girl, Ursa, Bizarro, and various Lantern and Sinestro notables.
Last Laugh is free for legendary players or $9.99 for free and premium members. You can download it via the PlayStation Network or the in-game marketplace.
