Blimp puzzle
Look in your inventory and examine the disc Batman picked up
before fighting Mr. Freeze. It will divulge possible colors that
work with the Blimp puzzle. The combination is Purple and Green.
Make the color purple, "mix tubes", then you can make the color
green.
Rooftop Battle: Envelope A
When the clowns pursue Mary, you will go up to the rooftops.
Grapple hook up to her roof and beat up the white clown. Go up to
the next roof, where you are on a tiny balcony. Jump across, then
go in to see a thug run across a hall with the girl. Follow and he
will jump off the roof. Follow, look down, and drop to lowest edge.
Walk along to left until at the corner where the grapple icon will appear
Grapple over, go in the door and pick up Envelope A.
Gasworks: Envelope E
You will get to a room with two levels, each floor with two goons
on them. First, take out the goons. Then, look around on the lower
floor until you see a sewer pipe with boxes in the sewage. Carefully
glide down and land on the first box. Jump over the next few boxes
and pick up the envelope with an "E" on it. Finish the game and the
"Infinite Health" cheat will be available.
Hacking into Issac Evers files
Locate the second wire of the color you need (that is not
powered). You need to make the powered wire reach the non-powered
one. For example, if you work on blue, you need to connect the live
blue wire to the dead blue wire.
FunnyBones Warehouse lock
Instead of trying the 999 possibilities on the lock, look for
figurines like the one in the room near your starting location.
There is another one behind trucks and one outside the fence when
you get on the roof of the building with the first figurine. The
combination is 619 (from left to right).
Plant Electrocution 2: Envelope C
You will start the Plant Electrocution 2 level by sliding down
towards a few holes in the ground. The second hole is not lethal. Fall
into it and glide (to avoid trivial damage). You will see a lit area.
Glide down there and pick up the item you locate inside. Use the
grapnel to exit, jump out of the hole, and finish the slide. The
item you picked up should be the key to the door right beside the
vines behind the glass. Go inside and fight one of the "Plant Men".
You will find an envelope that has a "C" on it in the room. When you
finish the game, you can enable this cheat for all weapons and
unlimited ammunition.
Flash bombs
To use flash bombs press
Action
+
Guard. They
cannot be selected in the gadget/first person view.
Smoke bombs
In the level that is after the Batcave training, when you get to
the area with a Joker thug, look around the big square. You will
find a ladder in time. Climb up the ladder, then look around for a
box. Pick it up to obtain smoke bombs.
Bridge: Envelope B
Knock out the thug at the start of the level. You should see the
glowing item on the left when you begin. Climb the ladder and
jump/glide around the crate onto the other crate. Then, glide onto
the platform with the letter.
SWAT Chase: Envelope D
You will enter the elevator shaft. Ride the elevator all the way
down until it stops. Get off the elevator and wait for it to rise
again. After it rises, jump down to the bottom and use first person
mode to find the control box. Use a Batarang to disable it and the
door behind it will open. Stay clear of the elevator and wait for
the correct time to get in the open room. Inside the room is "Secret
Key 2." Get out of the room and ride the elevator up to the top. At
the top there is a door that is supposed to be locked. The key opens
the door, and inside is an envelope with the letter "D" on it.
Finish the game and the "Infinite Special Move Bar" cheat will be
unlocked.
