Nope, don't worry, you haven't slipped back through a time portal to four years ago. Or, at least, if you have, it isn't because of this news. The 2010 strategy RPG Mount & Blade: Warband is getting another DLC expansion. Viking Conquest is set around Britain, Norway and Denmark, and features a single-player storyline, the traditional sandbox mode and new multiplayer game types.
If you're worried that this will further extend the agonising wait until the release of Mount & Blade 2: Bannerlords (opens in new tab), rest easy. The DLC is being tackled by the makers of M&B: Warband's superb Brytenwalda mod (opens in new tab)—leaving TaleWorlds to continue working away at the sequel.
The expansion will be releasing into early access "soon". There's little in the way of additional details, but you can see some seafaring screenshots below.
