Difficulty Setting Trick:

This is a glitch that can come in handy. First, start a mission on expert difficulty. Next,

save in the middle of a mission and then exit back to the title screen. Now, change the

difficulty to novice. Do not load the save file with your current mission yet. Instead,

start a new game, and then do a soft reset (press SELECT + START). Finally, load the

save file with your current mission.

Now the game will still think your mission is on the expert difficulty, even though all

the enemies will be set to the novice difficulty. This can make getting the 10th and

11th level weapons a lot easier.
