As we mentioned on Twitter
this morning (you do follow us
, don't you?), today is the first legitimate day that you can mark off on the calendar towards the Storyteller Achievement
Feel free to check out the excellent, community-written guides on the achievement, but it basically boils down to you taking everyone's favorite Dark Knight to the bowels of courthouse to speak to Calendar Man on certain dates (holidays).
While some gamers may be quick to jump on the, "just take your Xbox offline and change the date" bandwagon, this is one of the twelve dates of the year that you will need to visit to legitimately get the achievement.
