Hint: Special moves:
Press Down, Forward + Punch + Kick.

Circle half way from down to where you are facing and press Triangle + Circle to use one of three specials.

Hint: Altron Gundam: Beam Trident Rush Attack:
Press Right, Down, Left, Right + Punch for the Beam Trident Rush Attack, which is not in the manual. Note: This assumes player is facing to the right.

Hint: Bolt Gundam: Double Ball Attack:
Perform the attack where Bolt Gundam unleashes his ball on a purplish chain. However, when it is in mid-flight, press the same combination of buttons again.

Hint: Sandrock Custom: Shotel Carnival:
Press Forward, Down, Left + Kick.

Hint: Burning Gundam: Combo:
When fighting in any mode, use Burning Fingers (Down, Left + Punch) and immediately after the attack is done use Sekiha Tenkyoken (Down, Right + any two Attack). Make sure you have at least one more special gauge left.

Press Back, Down, Forward, Down, Back + Triangle. Burning Gundam grabs the opponent and thrusts him back with Burning Fingers.

Hint: Score under three minutes in Time Attack B:
Use GP 02A (Gundam Physalis). Since you fight the four Huge Class Mobile Suits (Big-Zam, Neue Zeil, Dark, Psycho Gundam), they cannot or do not block much. Use the Missile Rain Attack, and try not to hit the Suits with the initial Missile Pod (as it does less damage). Let it open and do more damage.

Hint: Destroying Mobile Armors:
Immediately boost over to the Armor's backside and use an attack that cannot be blocked until one or two of it armor gauges are gone. After this, continue unloading all of your ammunition/specials into it. If it turns around or tries to jump on you (Big-Zam usually), dash in front and boost behind when you get a chance. Most Gundams can drop it without losing any health, if your dodges are timed correctly. Note: Some Gundams consume ammunition much faster than others.

Hint: Blocking the unblockable:
The following Gundams can block unblockable techniques such as Beam Sabers: Master Gundam, Wing Zero Custom, and any Gundam with a Bubble Shield (any two attack buttons). With Master Gundam, use his Master's Cross (Down, Back, Punch). With Wing Zero Custom, use his Bird Tackle (Down, Back, Kick) or his Rising Bird Tackle (Down, Forward, Down, Kick). This move can damage the opponent, unlike the Master Cross.

Hint: Manual special moves:
You can alter the following so your Gundam performs different actions while performing a Special. These moves are possessed by Dragon Gundam, Deathscythe Hell Custom, Epyon, and possibly others. With Dragon Gundam, use his Dragon Flame (Down, Back, Punch) and press Up or Down to move the Dragon Flame in that direction. You can also use this move in the air. With Gundam Deathscythe Hell Custom, use his Phantom Move (Down, Back, Kick) and hold any direction to appear in that direction. This move can also be used in the air. With Epyon, use his Charging Energy Sphere (Down, Forward, Punch) and hold any direction to travel project Epyon towards the opponent. Epyon can plow through any move with Charging Energy Sphere. This can also be used in the air.
