Let's all hope you remembered to make your mother feel extra special when Mother's Day
came around again last month. Now, today (June 16th) is your annual opportunity to make sure that you do something similar for your dad, as Father's Day is celebrated in many countries across the globe. What's more, you'll have to make time to visit the Calendar Man and put a cross in the corresponding box towards the following achievements in Batman: Arkham City (Xbox 360)
and Batman: Arkham City (PC)
Calendar Man will come knocking again soon!
