DC Universe Online fix this morning, only to be greeted with a hanging connect screen and an urge to Hulksmash my keyboard. After my DC fan card was revoked, I remembered that it's patch day, and SOE has said to expect a five-hour down period to pave the way for Game Update 21.
When the game comes back, there should be a new PvP map, though the Inner Sanctum is only playable if you've purchased the Hand of Fate DLC (or if you're a subscriber/Legendary member). The devs are also adding a handy auto-loot feature and a number of tweaks to missions, alerts, challenges, and more. Full details are available via the patch notes.
