  • Easy Paragon and Renegade points

    Throughout the game you will unlock training to redistribute your skill points. Talent Mastery adds a certain percentage to your Paragon/Renegade. Respec and distribute them into your Mastery repeatedly until your Paragon and Renegade are full.

  • Easy materials

    To find some easy mining planets, go to the Micah system in the Vallhallan Threshold, and look for the three planets hidden in the asteroids. They are all "Rich" planets with a lot of materials on them to help with your upgrades. -From: Psychotic Elf

  • Easy skill points

    Recruit Morinth to get the Dominate skill, and get a large amount of Element Zero. Buy the Advanced Training upgrade, and select Dominate. This will result in a bonus skill point, which is then used by the Retrain Powers upgrade. Repeat this process to get another skill point.

  • Easy Geth Pulse Rifle

    Change the difficulty to Hardcore before you land on the planet. Successfully complete Tali'Zora's recruitment mission to find the Geth Pulse Rifle in the room where you find Tali. You can then change the difficulty back to its original setting.

  • Cryo Bomb

    This trick requires any Biotic that lifts your enemy off the ground and the Cryo Bomb tech. Use the Biotic to lift the enemy off the ground, then hit him or her with the Cryo Bomb while they are still under the Biotic's effect. This will cause him or her to be stuck in a permanent falling state, where they are not capable of causing any damage. This is very helpful when trying to prevent the deployment of Harbinger, as once he enters the glitched body he cannot move. Thus, you can kill him at the end of a fight to prevent him from jumping into another body.

  • Rapid fire M-920 Cain

    Shoot the M-920 Cain, and keep [Fire] held while pressing [Reload] after each shot. The shots will keep firing during the previous shots' explosions.

  • Getting Dominate ability and keeping Samara alive

    Dominate is a very useful Biotic ability that allows you to control organic enemies and turn them into allies, similar to the Hack ability that controls synthetics. In order to get this ability as a Loyalty mission bonus to use for your character, you must help Morinth kill Samara during Samara's Loyalty mission. However, it is possible to keep Samara on your team but still get Morinth's Dominate ability by using the following trick. Play Samara's Loyalty mission up to the point where Samara confronts Morinth. Save the game immediately before the confrontation. When you must choose who to eliminate, choose the option that allows Morinth get the upper-hand on Samara and kill her. Create a separate saved game file. Go to the ship, and talk to Morinth. Load the previous saved game, then have Samara kill Morinth. You will now get to keep Samara as a squad mate and have Morinth's Dominate ability when you choose a bonus Loyalty power to add to your character in the prototype upgrade screen.

  • Romancing Yeoman Kelly Chambers

    Talk with Yeoman Kelly Chambers often, and choose the kind responses. Invite her to dinner when you get the option. Do not let Kelly die during the final mission, and select a loyal escort for the crew in the final scene. After completing the game, talk to Kelly. You will get an e-mail from her. Go to your quarters, and invite her up using your console to get the romance scene.

  • Ending with both Jack's and Miranda's loyalties

    Do not play Miranda's loyalty mission at first. Instead, wait for Jack's mission to become available, and play it first. After the mission when they are fighting, support Jack. Miranda's loyalty will be low. Then, play her loyalty mission to get it back.

  • See Legion dance

    Go up to Legion in his quarters. Highlight him, but do not talk to him, and eventually he will do the "Robot" dance.

  • Bizarre dialog with Legion

      1. Take Legion to the Citadel. Talk to Anderson and the customs officer.
      2. Take Legion to the migrate fleet on Tali's Loyalty mission. Security will force you to remove him unless you can persuade them otherwise.
      3. Take Legoin to recruit Tali. She will try to shoot him.

  • Amusing surveying responses

    Go to the Local Cluster, and survey Uranus. Instead of the usual "Probe Launched" response, the voice will instead make Uranus jokes such as "Probing Uranus" or "Really Commander?"

  • Humorous dialogue

    Wander around the ship in-between missions to hear some funny quotes. Stand next to Jeff "Joker" Moreau (the pilot) without interacting with him. You will hear him say things such as the following:

      "Why is it always claws and guns? Can't we piss off a fuzzy planet? Still dangerous, I know. But hey, bunnies."
      "Two years and everything hits the crapper. That'll teach you to die on me."
      "You know what I hate about deep space? Crap radio stations from two centuries back. My gosh, we were idiots."

    Stand near the two engineers near the Mass Effect Core to hear the following:

      Engineer Daniels: "Did you know we're sharing our deck with a krogan?"
      Engineer Donnelly: "Well that's just peachy."

  • Baldur's Gate series reference

    Space Hamster is available on Illium. Once you go into your cabin and select him, he will come out and do the same "Squeek" that Boo did, who was Minsc's "Intergalactic Space Hamster" from Baldur's Gate and Baldur's Gate 2.

  • Legion's gaming history ("The Lair Of The Shadow Broker" DLC)

    At the end of the game in "The Lair Of The Shadow Broker" bonus downloadable content, examine the terminal that has all your teammates' dossiers. Read Legion's dossier to find out that he is a gamer. It will list the games he has downloaded, his leaderboard scores, and other information about his gaming past.
