Defeating Abyss:
Select Cable. For Abyss' first form, just block his attacks and then press Y to shoot. Repeat this until he dies. For his second form, distance yourself far as possible and shoot. Repeat until he dies. For his third form, just use Cables Hyper Viper. It takes off 90-95% of his life in one blast and will be a 115-130 hit combo. Then, just hit him once or twice with any attack to defeat him.

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.

Abyss' first stage:
Defeat Abyss with any time limit in arcade and score attack modes. His first stage will be unlocked in training and versus modes.

Change clock in background:
To change the time of the clock in the background of the clock level, simply change the PlayStation2's system time.

Continue attacking:
Press Start immediately after winning the match to move almost everywhere and have the ability to continue hitting the defeated character.

Hint: Hayato: Profile:
Hayato's plasma combo variations make him a strong combo player, but most special moves lack quick recovery time and leave him wide open for an opponent to counter. Hayato's sword gives him decent reach, but only an above -average to expert player should select him up for assist type --,use his expansion type.

Hint: Hayato: Combos:
Thirteen-Hit Plasma -Sword Combo: Get your hyper gauge to level one. Jump in deep, press LP, while still in the air press LK,LP, LK, HP, Down, Down/Right, HP, Down, Down/Right [LP, HP] for seven hits.

Hint: San San: One hit kill on Spider-Man:
Use San San's Eating special and have the damage on high. Spider-Man can be defeated with one special.

Hint: Tyrant: Blow him up:
Send out the Tyrant. After he is done with his combo and starts yelling, press the combo for her rocket launcher and he will explode.

Hint: 114-hit combo:
Select Gambit, Iron Man, and War Machine, then get a level 3 hyper combo gauge and do all their hyper combos (L + R). It should do a 114-hit combo. If not, try starting the Hyper Combo with another person.

Hint: Unlimited chain supers:
Note: This trick only works in training mode. Set the combo gauge to infinity in the training menu. Then, start a super and start another one. This can be done an unlimited amount of times. This works best with characters who have beam supers.

Hint: Easy special:
When your special meter is at 3 or higher, press L + R to do any character's special.

Hint: Easy points:
You can get ten points a minute if you go to training mode, choose a character and opponent, then leave the game on for about five hours. Note: Do not pause the game.

Plug in a second controller, go to 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. You will get 100 points for each match.

Successfully complete all survivor mode, with any EX set if needed. Attempt to create an EX groove greater than 4000 points. Answer "Yes" and the game will allow you to do so.

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). When you begin at the first stage, make sure Cable's out first. 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.

Hint: 90% damage:
Choose Iron Man, War Machine, and Cable as your team, and make sure you choose projectile as their ability. Charge your super meter higher then 3, and press L + R (default for partner A and B actions). 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: An advanced part of this trick is to wait until your opponent uses his partner in battle, then use the attack. The result is devastating.

Hint: 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 (L=R). It should kill the opponent in one hit. This move was tested on Cable, a medium damage taker.

Choose Juggernaut, Incredible Hulk, and Zangeif. When at level 3, let Juggernaut be your active character, get very close, and press L + R 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.

Hint: Breaking the house in the clock tower stage:
In the clock tower stage, use Spider-Man's special of flying kicks and punches when the opponent has low life so when he dies he can break the house. Note: You have to make sure that Spider-Man pushes him to the right.

You can also break the house in the clock tower stage with Juggernaut using his Juggernaut Punch. You must push your enemy to the right when the enemy has little life remaining.
