Secret Ship Hatch

Easter Eggs

On a small unassuming wooden ship in North Gotham Dock's Industrial District, beside a flashing red buoy, lies a secret hatch that leads down into the rather eerie interior of the ship. To gain access to it, you'll need to stand above the outline of the hatch and hack into the Gotham Municipal Network using the password CITYOFTERROR. The hatch opens and you're free to enter.

Arkham Island

Easter Eggs

Take a look across the Northeast perimeter wall into Arkham Island, and you'll notice that's it's full of the titan-enhanced ivy plants from the previous game in the series, Batman: Arkham Asylum.

Big Head Mode

Easter Eggs

Every game should have a big head mode, and thankfully Arkham City does. To activate it, whip out your cryographic sequencer and hold the LB and RB triggers down at the same time. With these held, rotate the analog sticks 10 times in opposite directions from each other (one clockwise, one counter-clockwise) to unlock big head mode for both Batman and his enemies.

Killer Croc

Easter Eggs

After defeating the nefarious Ra's al Ghul, head into the sewers and search for a wall with a button (that doesn't look at all out of place). Hit the button with a batarang to summon a killer croc (only slightly less out of place than the button).

Secret Radio Messages

Easter Eggs

While looking for Riddler frequencies, you may happen to intercept curious messages with someone reading off numbers. The numbers are codes to secret messages, and take some cracking to figure out. One of the codes, once cracked reads: I will return Batman. That simple code can be solved with the formula A=1, B=2, etc.

Another code dishes out the numbers: 3 20 26 18 26 16 24 1 11 4 24 9 3 8 5 2 12 18 6 16 7 11 3 10 17 5 13 4 21 8. The formula for this one is different, and not quite so easy to crack. Can you figure it out?

Reference to TV Show (Lost)

Easter Eggs

If you're one of the millions of fans who made Lost one of the most popular shows on television, you just may catch a reference to the series within Arkham City. It occurs during the Joker's short speech during the main storyline, a speech which makes specific mention of television shows before the actual reference. So pay attention when you reach that point and see if you catch it.
