Players of Batman: Arkham City (Xbox 360)
and Batman: Arkham City (PC)
will have noticed a date-sensitive achievement in the game. On a special day during each month of the year, players are required to go and visit Calendar Man in order to get the Storyteller achievement
Players who haven't resorted to changing their date settings offline will be pleased to know that today's Thanksgiving celebrations are another of those special occasions. This will be the second opportunity for Xbox 360 players, who were also able to make use of Halloween for their first visit. For PC players in North America and Australasia, this will be your first opportunity. Unfortunately for PC players in Europe, Thanksgiving comes a day too early for you.
The next date that players will need to make a note of is Christmas day. For a full list of dates, check out the great work of the community solutions.
