Get Tactics Battle Mode

Beat story mode once to unlock Tactics Battle Mode and to unlock additional playable characters there, beat each level with each available characters in Tactics Battle Mode.

More Mobile Suits in tactics battle.

To get more mobile suits is easy. All you have to do is beat the three levels with a certain mobile suit in tactics battle mode, and get a star for each level.  Don't fail the mission or you won't get a star.  To get all the mobile suits,  spot as many different ones as you can in story mode.  But you won't see them all, and you can still get them by just beating tactics battle mode. You can only play as them in tactics.

Different Color GM, Gundam, and Zaku II in Tactics Battle

In Tactics battle mode when selecting a mobile suit, press either of these combinations: L1+L2+X; R1+R2+X; or L2+R2+X.  Highlught the mobile suit, then enter the code, holding the buttons down until the "Now Loading" screen appears.
RGM-79 GM=L1+L2+X, R1+R2+X, or L2+R2+X will change the color to dark gray (unpainted).
RX-78-2 Gundam=R1+R2+X will change it to a black and white mobile suit.

If you enter this code with other mobile suits, you will change the weather of the mission stage and maybe even the difficulty.

How to beat the zock

To beat the Zok is lock on to the Zok save beam rifle of bazooka ammo.Then use the R1 and L1 buttons and run and shoot at it till it dies. I don't know the exact number of shots it takes to kill it.

Get Garma's Suit In Tactics Battle

To get Garma's Zaku II Custom play the story mode. You can't do stage select. Don't worry you wont lose anything you have already saved. You only have to play to mission 2 once there shoot down 6 of the dopps.( I recomend the beam gun.) After you have shoot down 6 Garma will arrive in a suit not in a plane. Finish the mission save and then play the Tactics Battle until you get him. If you have all suits but Garma's tehn just play mission three with the kamper( suit with the shotgun ) and get a A or better thn you should have it. ( IF ANYONE KNOWS HOW TO GET RUMBA RALS ATTACK A MOVIE THEN PLEASE SUBMIT IT!!!) GL and HF
P.S.    PSA CLAN  RULES!!!!

See Garma's Zaku II

On Winds of War level shoot down 7 or 8 dopps then wait until Amuro says "That's the squadern leader?" then you'll see three Zaku 2. Two are normal and the middle one is light orange and dark green. WATCH OUT! Because he has a BFG and 4 vuclans

See all Mobile  Suits in Gallery

Try to see as many different mobile suits as you can in story mode.  Fight them you will have a better chance of seeing them in the gallery.  Even if you don't see them all they are probably in tactics battle mode.  Unlock them in tactics and they'll be in the gallery. Don't forget to save! Also who knows how to get Matilda part 4 in the gallery to watch?  

Unlock all B.G.M. songs.

To unlock all songs depends on how far you get in the game.  Once you get all the mobile suits in Tactics battle mode and get alot of videos in the Gallery.  You will probably have all of them.

Tactics Movies!

Don't stop after you get all the mobile suits in tactics mode!  Get the ranking of Colonel, to get Federation Girls and Hail Zeon! videos. Also you should have most videos over all unlocked. 

Get Ramba Ral Attack A and B levels.

For the guy asking this how you get it.  Really this is just random to get both levels. Just try doing all the objectives in the game for each level.  It's random I think.  My fourth time I beaten the game I got it.  But don't get mad if you can't get it the movies are exactly the same. (What a waste of my time!!!)

Hint: Final Stage

On the final stage you should choos the "mace" like weapon becuase the only enemies are other mobile suits. You can just lock on and keep attack, plus you have the advantage of not reloading.

Zock, Level 9

You should use a Hyper Hammer to attack him, because no reloading, but try to land on top of it. Don't just stand somewhere and attack you have to dodge the lasers. Does anyone know how many shots it takes though, I didn't count.

How to get Movie 4 Matilda

For the person who wanted to know how to get movie 4 Matilda all you have to do is get an E on any of the missions. i recommend mission 2 and destroy almost all the buildings.

Beat the Big Zok

I think its easier to get very close the the Zok and hammer him away. I found when i played that if you rotate and stay on his side not the front or back he cant hit you even with his lasers. You know your too far when he can rotate faster than you can circle around him, with practice beating this big guy really gets easier than any other MS in the game.

Level 9 and the Zok

For those that have trouble with level 9. It's actually the easiest level in the game. It's better to use the LASER instead of the mace. The mace's distance is bad which means they can hit you with anything before you even get to them. Use the laser and don't be afraid of wasting its special cuz u won't need it for the Zok.
THE ZOK: This guy is easy. Its easier if you hit him with a supershot but if you don't hit him 25 times and he should be dead. Trust me I always get a S+ rating. 

Get good ratings on Missions

Ok, Ever since I saw the cheat that said you had to beat the game with an A+ rating for Wing gundam and S+ for Wing Zero, I have tried over and over. In my experience, you get the best rating if you just beat the levels by skipping the crap in the way and hitting the main targets (dark red). Do this really fast and try not to get hit at all. It works for me, but I got an A+ rating and got nothing. Can some one plz confirm that Wing zero/Wing Gundam cheat! Note: The laser is the best weapon to use in every mission except the one where u fight the 3 DOMs- I used bazooka for that level and got an S+ rating!!

Kill the Gaw Carrier in one hit

On the third stage of the story mode pick the Hyper Hammer as your weapon. During the stage when a Gaw comes you can jump on top of it. Once there, lock on to it and hit it with the hammer. The hammer will go through the ship killing it in one hit.

Easy Grades

To easily get an S+ or S- on any level, first
go to options and put on auto save. Then after you beat a level see what grade you got. If you didn't want that grade hit reset and the game will be saved so you can try again.

Beat Zock easely

message: What I did was I locked onto it and flew around firing my beam rifle. After it ran out I took out my beam saber and flew up to it and kept on slashing it as many times as I could. This disables him to attack because he is being hit all the time. It worked for me when I was almost dead so it should work greatly if you close to full health.

Gundam Zeonic Front

This mysterious youth was sent from the L1 space colony cluster to fight against Oz. He goes by the alias Heero Yuy, after the martyred leader of the space colonies; his real name, like almost everything else about him, is unknown. Heero has been trained since childhood for his role as pilot of the Wing Gundam, an upbringing that has made him cold and ruthless. But thanks to his years of training, Heero has become a perfect soldier equally skilled in personal combat, explosives, and computer hacking.

Duo is a member of the scavenger organization known as the Sweeper Group, which sent him to Earth to battle Oz. Despite the hardships he's suffered in his young life, and the seriousness of his mission, Duo is always cheerful and good-natured. But when he goes into battle as pilot of the Gundam Deathscythe, striking from the shadows with its lethal beam scythe, he truly earns his nickname "God of Death."

The most mysterious of the Gundam pilots, the young man who calls himself Trowa was sent to Earth as the pilot of the Gundam Heavyarms. The cool, quiet Trowa has nerves of steel and superb reflexes, qualities which serve him well in his cover identity as an acrobatic clown in a traveling circus troupe. He also has soldiering experience far beyond his years. When combined with his heavily-armed Gundam, Trowa's tactical skill and combat ability make him a veritable one-man army.   Quatre is a young aristocrat, the thirtieth child - and only son - of a wealthy family of space colony developers. Though he's the most tender-hearted and gentle of the Gundam pilots, Quatre is just as brave and determined, and has defied his family's wishes in order to join the battle against Oz. Quatre is aided by a troop of forty loyal underlings and can draw on the Winner family's vast resources, assets which more than make up for his relative lack of fighting skill. Wufei is the descendant of a legendary Chinese warrior clan, who sent him to Earth to fight against Oz. This proud fighter lives by a strict code of honor, punishing evil and enforcing justice as he sees fit. Wufei prefers to operate solo, since he has little patience for lesser warriors. These high standards make him equally contemptuous of his own failings in battle. The only ally he trusts is his Shenlong Gundam, which he has nicknamed "Nataku" after a hero of Chinese mythology.
