This is one of the hardest trophies in the game. You need to be very thorough and search everywhere. Always send Mooch up into vents you can't reach, check up on the hanging lights in rooms, try not to skip any areas. For instance there is an area where Speckles will tell you he thinks he knows a shortcut, and if you choose not to go that way the door will not open when you come back and you will not be able to get the chips from the enemies and boxes in that area when you come back.
There are chips in boxes in the training level, don't miss those.
Make sure you kill every enemy, don't skip any. This includes the satellite dishes that just block your path with a red wall and every enemy that drops chips. The only one that doesn't drop chips is the small spiders that slow you down. If you kill an enemy that is far away send Mooch to grab the chips or try to pull it in by holding R1.
Sometimes when you die and there are chips you haven't collected from enemies they will not be there when you respwn. I'm not sure but this only happened sometimes, so just be careful to try to always grab chips as soon as you beat an enemy even if you're still in the middle of a fight.
*Here is an alternative way to getting the Master Agent trophy. Thanks to Roughdawg4 for submitting this tip:
"I noticed in my Super Agent game that when I used plasma like crazy, it dropped plasma. So I thought, what if I didn't use any guns and only my whip so my ammo was always full. Well since I don't use ammo (most of the time), I get nothing but chip drops. I should easily have 40,000 by the end of the game and no extra farming is necessary, just try to kill everything with your whip.
These are the only things I didn't kill with my whip (forgive me I don't know names):
The Fans
The machine with the shield and laser
And the 2 big flying machines (one shoots projectiles and the other missles).
Everything else use your whip. And remember you have 10 lives on easy mode so you can afford to die a few times."
One note if you do decide to go this way: Make sure that you are extra careful when you do use your guns as you should be going for the 80% accuracy trophy also, and if you are mostly using your whip you will need to be extra careful to miss as few shots as possible with your guns. Remember, 80% is 8 out 10 shots that need to hit, so you do need to be as careful as possible.
