I dont take credit for any of these since I would be generally bad forum but here is the url where these came from incase you would like to see the source.
LinkInfinite Paragon/Renegade Points:On the Noveria planet, go 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 will do it, and then talk to Quinn. Tell Quinn that he should testify (top left option). When he refuses, select the Charm option (top left) for Paragon points or the Intimidate (bottom left) for Renegade points, and end the conversation. Talk to him again, and ask about the Matriarch. When he gets done talking about her, select the "Other questions" option (bottom right). You should now have the option to ask him to testify again (top left). He will refuse, and you will be able to use the Charm or Intimidate option again to gain another 24 Paragon or Renegade points. Repeat this process as many times as desired. You can also easily get the "Paragon" and "Renegade" achievement with the glitch.
Infinite Paragon Points:On the planet Eletania in the Hercules system of the Attican Beta cluster, during the lost data module quest there is a moneky in a cave with the data probe. In order to use this glitch you must NOT kill any monkeys on the planet. Once you find the monkey that give syou the data module, save your game. Once saved, reload it and click the monkey again and again, earning 4 paragon points per click. Do this as much as you wish to fill your Paragon points to their max and get free skill points in Charisma.
Note on normal Free Charm/Intimidate pointsYou get 1 free Charm and 1 free Intimidate point when you become a Spectre. You then get 1 free Charm/Intimidate point at 25%, 50% and 75% of the appropriate alignment. So you can get up to 4 free Charm and/or Intimidate points per game. You can not *max* the skill in a single game, you'd need 3 games on the same character to do that.
You need 5 points in charm and intimidate to get the options. so about two playthroughs going on just free points before you can do this.
Assuming you get 4 points from the first two games then on the third game you can get a total of 4 free points for charm and intimate . one point from becoming a Spectre and 3 points from maxing out paragon and intimate with this glitch.
Infinite Money GlitchAfter helping Dr. Michels [Doctor in the wards on Citadel] with her extortion problem, she gives you a discount in her store. This also increases the price she pays for stuff you sell to her. If you go to the buyback screen, you can buy it back for the same price she paid. However...the buyback screen is shared amongst all shops, and an item doesn't save the price it was sold for. So any other shop will have the same item on the buyback screen, for less money.
Example:
Buy HMWSG VII Shotgun at C-Sec.
Sell HMWSG VII Shotgun to Dr. Michels for 98000 credits.
Buyback HMWSG VII Shotgun from C-Sec for 56000 credits.
Repeat until rich.
Obviously this doesn't work too well with a cheap item, since each run you'd only get a few credits, so you need to own an expensive item in the first place. And once you have enough money to buy an expensive item, it's not hard to earn enough to buy more expensive items the normal way.
Finding Better Armor/Gear:
First, buy as many company licenses as you can. Once you have them all, or at least the one for the company you want the gear from [ie Colossus] fly to one of the main worlds and dock. Leave the normandy, and go to the planet, run around a little, do some shopping, see some sights etc... just spend a few minutes off the ship.
Then, come back to the normandy and go downstairs and stand in front of the requisition officer. DO NOT TALK TO HIM YET!
Save the game!! After you have saved the game with you standing in front of the officer, THEN you can talk to him. If you talk to him prior to saving then everything up to this has been pointless as his inventory is locked and will not change.
However, if you did it right, you should be able to talk to the Req Officer and look at what he has for sale, if you dont see anything you want, reload that new save, and look again, it should have changed his inventory. Lather rinse and repeat until you find the gear youre looking for.
Infinite Experience Glitch (needs a little bit of revision)On Therum right before you rescue Liara:
After you activate the mining laser to get behind the barrier but before you actually talk to her. When you approach her prison, look at the floor. When you pass over where the pattern changes to the sterile tile look experience will be awarded (about that point, you might have to move a little farther in). Save the game then load that save. You will be awarded more experience, save the game again and load.
Then save/load a third, fourth, fifth.... etc, creating a new save each time, Until you have achieved the desire level.
Additional from another PostersElsewhere on the net peeps say you have to use the mining laser first but it worked fine for me as soon as I got off the lift that takes u down to where the laser and Liara are.
I saved my game as soon as I got off the lift and b4 I spoke to Liara. Decided to reload it because I made a 'wrong' conversation choice and as soon as the game loaded it awarded me about 200 exp. Figured it must have been a glitch so I reloaded a previous save at the top of the eleveator and it didnt give me any extra exp. I also reloaded saves after speaking with Liara but b4 using the laser, and after using the laser, and in both cases I go the 'bonus' experience points.
