If I'm honest I'd totally forgotten that The Elder Scrolls Online [official site] is a thing that still exists. ZeniMax haven't, though. In fact they've just launched the latest DLC for the MMORPG: Dark Brotherhood.
If you have even a passing familiarity with Elder Scrolls games you've probably worked out that the Dark Brotherhood stuff is about trying to join the franchise's guild of assassins:
A merciless guild of assassins rises to power in Tamriel, and your murderous talents make you a prime recruit. Explore the Gold Coast and discover if you have what it takes to become one of Tamriel's master assassins in the Dark Brotherhood DLC game pack. From the bustling port city of Anvil to the Great Cathedral of Kvatch, the business of the Brotherhood consists of murder and mayhem—and business is good! Join the Brotherhood, enter the Sanctuary, and accept your first contract from the mysterious Speaker. Kill well, assassin!
I feel like that's a lot of responsibility to just give to some rando who turns up at the Sanctuary. Like, you just give them a contract without making them do a proper internship? I mean, in the documentary, Game Of Thrones, there is a LOT of faffing about and training and more faffing and posturing and having conversations that go precisely nowhere. The Speaker in TESO doesn't even seem to ask for your references.
Oh, hang on - maybe this bit is the vetting process?
"Enter any Outlaws Refuge and approach an assassin by the name of Amelie Crowe. Speak to her to begin the “Voices in the Dark" quest. Progress through the events of the quest—they'll lead you to Anvil and put you on the path as a Dark Brotherhood initiate. (You can also accept the “Voices in the Dark" quest by purchasing the DLC and navigating to the DLC tab in your Collections menu.)"
There's also this trailer, which is mostly just players sneaking up behind someone and stabbing them and then showing it again from a different angle. I mean, I guess it's honest in terms of how stabbing someone from behind works in the game but it is seriously not selling me the experience:
There's also a minotaur and poisoning.
Anyway. The deal is the same as with previous TESO DLC. There's the specific Dark Brotherhood stuff in one lump and the other lump is a patch that everyone who owns the base game gets access to.
The DLC is 2,000 crowns which is TESO's in-game currency. It works out at about a tenner if you want the direct conversion, although you can't just buy 2,000 crowns. You'd have to get one of the larger packs and just have some crowns left over to fritter away on whatever else took your fancy, so it's sort of really £14.99 and then 1,000 crowns in change.
Alternatively, you can get access without paying extra if you have the TESO Plus membership thingy, which is their premium paid account model. It's £8.99 for 30 days so it's technically cheaper than just chucking crowns at the problem and you get access to all the DLC but that only lasts as long as your Plus membership.
