Mass Effect

Complete the game once.

You will need at least one high level character to do this. Play that profile and sell anything you want your other, lower, profile to have and save the game. After activating the lower profile, go to a shop keeper and access the "Buy Back" option. Your high level equipment will be in the lower profile shop.

Infiltrators combine combat and tech abilities, and specialize in killing or disabling enemies at long range. Infiltrators are trained to use OmniTools, but the focus is on decryption and offensive abilities rather than healing. They can train with pistols or sniper rifles, and can learn to wear medium armor.

Here's a great way to score infinite Credits. Follow the steps below in order to do so...

1.) First, fulfill the side quest involving Dr. Michel (from the Med Clinic) and her blackmailer. After the quest is complete, you'll get a discount from all of the goods she sells.

2.) Start selling her all of your expensive equipment. Then, travel to the Wards Markets and talk to the merchant named Expat. You can buy all of your stuff back for cheaper than you sold it off.

3.) Head back to Dr. Michel and sell off your stuff again. Repeat this process as much as you want for as much profit as you desire.

When you reach the Hercules System in the Attican Beta Cluster you will receive a mission to recover a "lost data pad" from the planet Eletania. Once you have found the data pad on one of the roaming local species(called a "monkey" in the game) in the mine you will be awarded approximatly 6+ paragon, save the game immediately. Once done, load the saved game and you should be able to continue to click on this monkey infinite amounts of times.

On the planet Noveria, head to the hotel bar and look for a Turian named Lorik Quinn. Accept his quest to steal the data from his office. Once you get the data, the receptionist will ask you to get Quinn to testify. Tell her you'll do it, and then go talk to Quinn. From here:

1. Tell Quinn that he should testify (top left option).

2. When he refuses, select the Charm option (top left) for Paragon points or the Intimidate (bottom left) for Renegade points and end the conversation.

3. Talk to him again, and ask about the Matriarch.

4. When he gets done talking about her, select the "Other questions" option (bottom right).

5. Now, you'll have the option to ask him to testify again (top left). He'll refuse, and you'll be able to use the Charm or Intimidate option again to gain another 24 Paragon or Renegade points.

Repeat steps 3-5 until you have all the Paragon or Renegade points you want.

Go to your Galaxy Map and travel to the Attican Beta cluster. You will receive a message from Alliance Command telling you about a downed recon probe that you must retrieve a data module from. From there, travel to the Hercules system and continue to the planet Eletania. After you reach the downed probe you will discover that a monkey-like native has made off with the Data module. Get back in the Mako and go to your map. You will see three native colonies. Go towards the one in the middle of the three. After that, go into the mining shaft and proceed through the tunnels until you reach the end. Search the two monkeys in that part of the shaft. One of them will have the Data module. Save the game immediately after getting the module. After that, reload the just saved game and continue to press A. Keep searching the monkey that had the Data module. Notice that your Paragon meter over the radar will increase each time you select the monkey. At about 300 Paragon you will receive an achievement named "Paragon". Note: If you have completed this assignment already this glitch cannot be done.

Every so often you may encounter a slow down on graphics and game play. If you have been playing for less than three hours and see the "Loading" text, release your controller for faster loads. If you have been playing for over three hours and the game play slows down, save and reboot your Xbox 360. This is because the Xbox 360 does not have an efficient way of clearing its memory for new information. Once the memory is saturated, the "lagging" game play happens. Because Mass Effect is so massive and everything is unique, it uses all of the available memory.

If you're driving around with the Mako on any planetary surface, whether on a side quest or during the game's main missions, you can use the Mako's machinegun and missile launcher to do massive damage to enemies. However, the extra power of the weapons means easier kills, resulting in lower experience points. If you want to get more experience (twice as much, in fact) get out of the Mako to kill enemies. You can weaken them as much as you want with the Mako, run them over, pin them down, and more. But be sure to deliver the killing blow outside of the Mako to maximize how much experience you will earn from the kill.

Use the following controls while in the Mako.

Press RB: Fire rockets.
Press RT: Fire main gun.
Press A: Undercarriage Rockets. This is useful for getting "unstuck", setting the Mako upright if upside down, and stabilizing from falling off a mountain.
Press X: Return to the Nomandy.
Press B: Exit Mako for on-foot exploration.
Hold LT: First person view.
Click Right Analog-stick while pressing LT: Zoom. Click it again for additional zoom. Click it again to exit zoom.

Successfully complete the game under the Insanity difficulty setting.
