Tomorrow, August 16th, marks the celebration of the life of Saint Roch. As is the case with many other important dates in the year, Calendar Man expects you to pay him a visit in Batman: Arkham City (Xbox 360)
and Batman: Arkham City (PC)
to mark that date off towards the following achievements.
Go on, take this opportunity to honour a man who travelled a lengthy distance to help others by going on an achievement-hunting pilgrimage tomorrow!
