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 -- hold L for the 
 second character and R for the third character at the versus screen.
 
 
 
 
 Change team order
 
 The order of your fighters will appear before a versus match, with 
 "1", "2", or "3". You can select the first and second fighters of 
 your team, and thus change the entire team order. 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''. Then, press the same button combos to select the second 
 fighter. Press Start to continue.
 
 
 
 Multiple character selection
 
 Unlock every costume and character to chose multiple people. For 
 example, player one could chose three Charlie's and the other player 
 could also chose three Charlie's.
 
 
 
 Cheaper hidden fighters
 
 Exit and enter the shop screen until the price of the hidden fighters 
 are lower.
 
 
 
 Change clock in background
 
 To change the time of the clock in the background of the clock level, 
 simply change the Xbox'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.
 
 
 
 
 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.
 
 
 
 Infinite 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.
 
 
 
 Easy special
 
 When your special meter is at 3 or higher, press L + R to do any 
 character's special.
 
 
 
 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.
 
 
 
 
 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.
 
 
 
 
 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.
 
 
 
 
 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.
 
 
 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.
 
 
 
 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.
