Yup, Aquaman, and the other guy

If you were playing DC Universe Online and thought to yourself, "You know, I like the DC Universe, but this game is just missing one thing - Aquaman," then all four of you are in luck. The new expansion for the game, dubbed Tides of War, is coming, with expanded lore and quests dealing with Atlantean ships and soldiers, as well as their rivals, the Mutineers. The war has broken the surface of the ocean, and now is on the border next to Metropolis and Little Bohemia, and you are called to put a stop to it. Four-person Alerts are available to all players, Villains and Heroes, level 5 and above, as well as open world missions and rewards. The full details are behind the link.
