Switch Characters During Match
Use the following to switch between characters in the middle of the game. For example if you choose Cable, Ryu, then Ken, but later in the second stage you want Ryu to appear first , then simply hold L1 for the second character and R1 for the third character at the versus screen.
Change Team Order
he order of your fighters will appear before a versus match, with "1", "2", or "3". You can change the entire team order by selecting the first and second fighters.. To select the first fighter, press LP + LK for the character marked "1", MP + MK for the character marked ''2'', or HP + HK for the character marked ''3''. After you have the order you want, press the same button combos to select the second fighter. Press Start to continue.
Multiple Character Selection
To chose multiple characters, unlock every costume and character. For example, player one could chose three Charlie's and the other player could also chose three Charlie's.
Cheaper Hidden Fighters
To lower the price of hidden fighters, simple exit and reenter the shop until the price drops.
Change Clock in Background
To change the time of the clock in the background of the clock level, then simply change the PlayStation 2's system time.
If you feel like getting a few extra licks in then press start after winning a fight to move almost anywhere and continue hitting the defeated opponent.
To get the ultimate combo, select Gambit, Iron Man, and War Machine, then get a level 3 hyper combo gauge and do all their hyper combos (L1 + R1). It should do a 114-hit combo. If that doesn't get the job done, then try starting the Hyper Combo with another person.
Press L1 + R1 when a character's special meter is at 3 or higher to do any character's special.
Choose Iron Man, War Machine, and Cable as your team, and make sure you choose projectile as their ability. Press L1 + R1 (default for partner A and B actions) after raising their special meter to higher than 3. The result should be all three of your team members will use their projectile super move, which will take care of the opposition provided they do not block. Note: To get an even more out of this devastating attack is to wait until your opponent uses his partner in battle, then use the attack.
Abyss' First Stage
To unlock Abyss' first stage in training and versus modes, defeat Abyss with any time limit in arcade and score attack modes.
To defeat Abyss in his second form, choose Cable. Keep shooting Abyss with the pistol and keep shooting till you have level 1 on the gauge. Execute Cable's Hyper Viper Combo. This should kill him -- if not keep repeating this pattern. The works if you are fast enough to kill him while he performs his short range attacks.
Choose Megaman, Cable, and Cyclops. Play under the easy or medium difficulty setting. At Abyss, use Megaman then jump behind him and shoot. During his second form, use Megaman and continue shooting at him. You should have a level three power bar by now. At Abyss' third form, wait. He always dives down before attacking. When he reappears, do a Triple Hyper combo. If the game is set on very easy and high damage, Abyss should die in one hit.
You can get ten points a minute if you leave the game running for about 5 hours in training mode after selecting a character and opponent. Note: Do not pause the game.
To get 100 points for each match, plug in a second controller, go to the options, change the time to 30 seconds, and turn up the damage. Go to versus mode, turn the handicap down on controller two, and fight.
To get easy points in arcade mode, fight up to Abyss in any difficulty on high damage. Your best difficulty setting is recommended. Once at Abyss, intentionally die on purpose multiple times. Continue, then die again. You will get 100 points every time a continue is used. When you finally choose to defeat Abyss, you will also get 50 points times the difficulty setting.
Enter the options screen. Select "Game Option" and set your difficulty bar high, choose the Turbo 2 speed, and have unlimited time. Put the damage bar on high. Go to arcade mode and choose any character with Cable (for example, War Machine, B.B. Hood, and Cable). Make sure Cable's our first when you begin the first stage. Keep shooting with the pistol until your third opponent's life bar is half full. At this time your level gauge should be past 3. Use it at the correct moment and you will see more than 80 hit(s), plus the Perfect. You now have more than 300,000,000 points. Repeat this for the rest of the game. When you get to Abyss, be sure not to have him defeat one of your characters. Just keep shooting Cable's pistol until you get to his last form. On his final form, when Abyss shows up again, make sure your level gauge is at 3 or more to blast away.
One Hit Kill
Choose Juggernaut, Iron Man, and BB Hood (in that order). Put them all on their recommended assist types. Get 3 Hyper Combo bars and link them all together (L1=R1). This should kill just about any opponent with one hit. This move was tested on Cable, a medium damage taker.
Choose Juggernaut, Incredible Hulk, and Zangeifet. Let Juggernaut be your active character when you reach level 3, get very close, and press L1 + R1 to make them all do their hyper combos. This will instantly kill your opponent's character. Note: This attack best works when your opponent is in a corner.
