Play as Mokap-
Successfully complete all missions in Konquest mode for all fighters. Then, highlight Cyrax at the character selection screen and hold Down.

Play as Raiden easier-

After the appropriate costumes are unlocked in the Krypt, press Start at the character selection screen to access the new costume.

Random character select-

Versus mode skill select-

FMV introductions-
Allow the game to enter demo mode to see the FMV of the first Video Teaser from Mortal Kombat: Deadly Alliance with Scorpion performing a Kata. Other characters (Kitana, Quan Chi, and Frost) will perform a Kata as well.

Background FMV sequence-
At the main menu, press Y and a movie screen will appear. It shows the story leading up to the start of the game.

Play as Cyrax easier-
You would have to have at least 462 Ruby Koins and open Krypt PD (to get 1056 Platinum Koins) and get the rest of 3003 needed to open CN for Cyrax. You can get extra Platinum Koins in the following Krypts: FV (83 Platinum Koins needed for 243 platinum Koins); PK (157 Platinum Koins needed for 475 Platinum Koins); WS (44 Onyx Koins needed for 165 Platinum Koins); and NG (63 Sapphire Koins needed for 252 Platinum Koins).

Defeating Moloch-
Play as Quan Chi, draw your weapon, then hold Away and press X, Y(2). Keep repeating this for an easy win.
Faster Test Your Might mini-game-
To end the "Test Your Might" mini-game in arcade mode faster, press R once you get your strength above the marker. You do not have to hold it for the full amount of time.

Easy wins-
Note: This trick can only be done with Sub-Zero, Kung Lao, Li Mei, Cyrax, Shang Tsung, Frost, Reptile, or Kitana. You can impale your weapon into your opponent, making them lose life every second. The move varies, and with some you have to press the D-pad and the button. To find the correct move, press Start, select "Move List", then look under your weapon and it will say "Impale". All of them have to be close range, but Kitana can throw her steel fans. However if it hits and they block or dodge it, you cannot use it again until the end of the match.

Monk movement-
Remain idle long enough during Konquest mode and the "monk" will turn around and shrug his shoulders at you.

Easy Koins-
Note: This trick requires two controllers. Select versus mode and load a profile for each fighter. Each fighter must have some number of each Koin. Do a Wager then after that match is over, have only one player press R. Press Right and you will hear the sound, then press Up to bet Koins. Press R again and play that match. The winner will get the coins, but the loser will not lose any. Go back and forth with each fight to make each gain more Koins, thus making each match worth more because you can wager more. Keep holding Up until you do not hear the sound anymore to bet the maximum amount in time. Use the following to learn what Koins you are betting, as you will not be able to see:

Press Right, Up: Onyx
Press Right(2), Up: Jade
Press Right(3), Up: Ruby
Press Right(4), Up: Gold
Press Right(5), Up: Platinum
Press Right(6), Up: Sapphire

Additionally, enter the versus menu and load a profile for each player. Press R to display the wager screen. Then, max out the wager for one Koin type and select "OK" on both controllers. Back at the character selection screen, unload one profile then reload the same profile. Then, alternately unload the second profile and reload it. Press R to go into the wager screen again. If done correctly, you both should have won the amount of coins wagered. Repeat this for this same Koin type until you are satisfied. Then, wager one final time for a few Koins and finally complete a battle. After returning to the character select screen, you must press Y to exit out and re-enter the versus menu. Repeat this for the other Koin colors.

Note: Once you have 1000 Koins for one color, fight and save and redo it for the same color so you increase at a rate of 1000 Koins per profile load/unload. Then, repeat at about 10,000, so you get 10,000 per battle rather than 1,000 and so on. Also, when wagering hold Up on both controllers to increase the rate the Koin Kounter rises.

Rumors- Some say they have seen Smoke or Noob Saibot running around in the Krypt. It is possible to hear them running around if you listen carefully. Some believe that the Krypt is connected to one of Shao Kahn's old torture chambers. At 12:43p.m., some claim that the whole Z roll in the Krypt has disappeared. Also, you may hear whisper in the Krypt saying something along the lines of, "Time will lead you to Saibot".
Rumors or no???
