 Sword.

 Successfully complete and save the game in campaign mode with both 
 the Federation and Zeon. Select campaign mode again, and an "Extra" 
 option will appear. In this mode, all Mobile Suits from both sides 
 will be available in more difficult missions.
 
 
 
 Alternate Mobile Suite color
 
 Select versus mode and select "Choose A Mobile Suit" Find a mobile 
 suit on the Zeon side, but have the team you want to be on the Federation 
 side. When the level starts, the Zeon mobile suit you had chose 
 will be a different color. Note: This only works on Mobile Suits 
 and not Mobile Armors.
 
 
 
 Hijack Mobile Suits
 
 To hijack or steal a Mobile Suit in the story mode, you must end 
 a mission with an enemy Mobile Suit still alive but with some damage. 
 Chances are that if it is the only Suit besides you and your ally, 
 you will see a message similar to "You have received a stolen GM". 
 You can use it for ground combat." To get the hijacked Suits for 
 arcade and the versus mode, kill one in arcade mode and survive 
 the battle in which you killed it. When you open the versus mode 
 or arcade mode, it will be there, ready for duty.
 
 
 
 
 The Titans and the air and spacecraft
 
 To unlock jets, submarines, spacecraft , and Titan class mobile 
 armors, locate one in versus mode, weaken it, and deliver the final 
 blow yourself. If an ally does the final shot, you will not unlock 
 it. Once you kill it and save, it will be available for use in versus 
 mode. An example is the G Fighter. Mobile Suits can jump on and 
 ride it while the other player steers. Press R2 to cut thrusters 
 and sit there. Another example is the Byg Zam. It is a two legged 
 ball with a lot of particle cannons and a shield that makes it invincible 
 to beam weapons.
 
 
 
 Good fighting Suits
 
 Some of the best Suits for arcade and versus mode are the Zaku II 
 and the two GMs. All three of these suits have about 400 armor health 
 points, very good weapons at their disposal, and are quite fast 
 and good all around. Most people dismiss them as simple walking 
 targets but they can pack a punch with some practice.
 
 
 
 
 Defeating Big Zam
 
 Take out the Rick Doms by using Gundam with your Beam Saber, then 
 get behind the Big Zam and fire your Bazooka. Beam Rifles have no 
 effect. When you run out of ammunition, switch to Beam Saber, jump, 
 and slash.
