Another holiday, another twisted tale of classic Batman villain Calendar Man's misdeeds. If you think that's a lame theme for a bad guy, just wait until you hear what this guy's done on each holiday—today included. And you thought punctuality was a virtue.
He's located in the basement of Arkham City's courthouse, and hearing each of his stories will net you an achievement or trophy. By the way, you can also just take your system offline and change the clock to accomplish the same thing, but that's totally cheating.
Have you missed any holidays since the game's October release? Which story has been your favorite so far? Let us know in the comments or on Twitter, and be sure to check back again on St. Patty's day next month.
