In addition to the player-versus-player goodies the latest DC Universe Online downloadable content pack provides, Mark Hamill will be returning to voice The Joker, and he won't be alone.

"The Last Laugh" DLC pack also features Arleen Sorkin, who returns as Harley Quinn, a role she played in Batman: Arkham Asylum. Adam Baldwin joins the two as Superman, his first video game voiceover role since, well, DC Universe Online. The content is free for Legendary subscribers and can be purchased by free and Premium users via PSN and the game's website.
