Gundam: Federation vs. Zeon

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.

Enter Kyasubaru (katakana) as a pilot name.

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.

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.

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.

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.

Select arcade mode and play as a Federation pilot. Choose the first stage and wait until you get to a desert mission you should be fighting one Zaku2, one Gouf and an ADZAM mobile armor. Target the ADZAM and destroy it to unlock it in versus mode.

Select arcade mode and play as a Federation pilot. The easiest way to encounter it is to choose the fourth stage. Kill it to unlock it in versus mode. The only way to kill it with most Mobile Suits (or Gundams) is to jump up and hit its main body with your Beam Sword.

Select arcade mode and play as a Federation pilot. Choose either the third or fourth stage, and at the second to last mission you will fight a mobile armor called BRAW-BRO. Kill it yourself to unlock it in versus mode. Note: This will not work if an ally makes the kill.
