These will be the most difficult achievements in the game. It will require a near perfect run on Raiden Fighters Jet. First, you will need to collect enough medals to get the Eagle Pendent. You must have a slave ship and collect a medal that drops down and will float in front of the slave. Then collect other medals so that it grows. Once you get the eagle pendent collect it then get nine medals on the screen. When you do that they will explode and the medals will become gold bars worth 10,000.
These bars will multiply with each one you get up to 100k (10k, 20k, 30k, etc) but if you miss one (Let it drop from the screen), then you will start at 10k. I believe that the ones that drop from ships increase the multiplier and not the ones that are on the ground (don't fall after a period of time), but you still need to grab them. Again, you will have to get really good at memorization and take out everyone with bonuses. Good luck.
