Item and Robot shop
Beat the game once; the Intermission's Shop option will have a list of expensive Enhance Parts and Units from the FMP and SEED series for sale. Press [X] for units and [Y] for Items.

Easy money and experience
If you fail a stage, you will start again from the beginning but will retain any experience and money that you have earned. To take advantage of this, play a stage in the game where there are plenty of enemies or bosses to destroy. Destroy all but one enemy unit (preferably a Boss unit to prevent clearing the stage) and intentionally end the stage in failure (destroying all of your own units with MAP weapons, killing a certain character in that stage, etc.). You will be taken back to the Intermission menu with all the money and experience you have earned.

Money Glitch
Begin a mission, any mission. When your motherships appear, and you go to the select mecha screen, press [X]. Unequip all parts from mecha, and sell them. Then, begin the mission, and fail. You will be taken to the pre-mission screen, with all the money from selling the parts, and the parts you sold. Repeat as desired for infinite money. It's possible upgrade every unit to the max this way as soon as you obtain them.
