After you help the woman in the med bay from the thugs in the citadel station she will give you a discount on her items buy everything you can then go to the market place and sell the items you got then buy back then sell to med bay lady then repeat.
On the moon when you have to go and disable the rouge VI after you go to the last building and destroy the last node a message pops up with binary code on it.

Power Gamer requires you to reach level 50, and Extreme Power Gamer requires level 60. It is impossible to reach either one by playing the story alone, and it is impossible to reach level 60 on your first play through, because the cap is set to 50. The best way to accomplish it is to play every world and assignment, so that you receive the Completionist achievement. It gives +5% bonus experience, which adds up on your second play through. Second, whenever you land on a planet, do everything you find there. That includes salvaging all the debris. Second, do not use the mako for killing enemies other than the colossus, armatures, or dropships, because you only receive about half the experience for kills with the mako. There is nothing worse than sinking 12 hours of play trying to reach them, only to finish at level 49 with 1,000 experience to go.
Play as a War Hero Soldier first. By doing this, during your second play through you will have all of the money, weapons, and armor to use for the other careers.

When you land on The Citadel you will encounter people that already know you, but they don't like you that much. To get them to like you more all you have to do is become a specter then talk to them once more and this time they will pay attention.
When you go into the elevator make sure your team mates both have helmets on. When you press the elevator button turn your camera to in between them so they are the center of the screen.

On the planet Feros you will end up having to fight a giant telekineses using plant called the Thorian. When you go fight the Thorian you will have to fight an Asari who keeps resurrecting itself and Thorian Creepers, so bring shotguns and biotic powers to this party.
When your on Virmire you have one team mate arming a bomb while the geth are shooting at him, and on team mate with Salarians pounding the geth into the ground. Choose who ever is with the salarians, unless you want to fight a whole geth ship then save the team mate at the nuke, but going back to the geth ship is suicide, it's your call.
You won't be able to make a good shot on Saren when he is jumping around so wait until he stops to shot at and have your team shoot him or hit him with all the biotic powers, weapons, and overloadings that your team has until he moves again. Continue this pattern and Saren will fall to you in no time.
To Easily kill Saren before he is resurrected by Sovereign walk sideways avoiding his rockets while you are shooting at him, destroying his shields, or using biotic powers.
