Hades Gamma Cluster Hidden Missions
To play the hidden mission in the Plutus system of the Hades Gamma Cluster, get 75% Renegade. To play the hidden mission in the Cacus system, get 75% Paragon.
Easy Experience Points
To gain extra experience from battles, make sure to get out of the Mako for the final hit. You can weaken the stronger enemies from inside the Mako and then get out to finish them off. You will only get 60% of the experience if you kill enemies with the Mako.
When you are using the Mako, try to kill as few enemies as possible with it. You can even use the Mako sitting in the garage on Noveria that you can decrypt and use (only the guns), because it is worth the same as far as experience points earned. Most of the time you will gain more experience points if you defeat enemies with your own weapons. In the case of a Thresher Maw, Heavy Turret, or a Geth Colossus, just use the Mako's cannon and mini-gun to get them to a sliver of health, then finish them off with your weapons. You will gain the same amount of experience points as you would have if you had fought them entirely with your own weapons. The sniper rifle can also earn you more experience points if your character is trained with it. Be careful on planets with hazardous environments when using either of these methods.
Ensure Experience Points and Gamerpoints
After a major plot has been played, make sure to talk to your crew. This will give you experience points for clues and boost your crew's morale.
Finding All the Elements
The best way to find the elements, minerals, and anomalies on planets that you can explore is to drive along the edges of the operational area (the red area). Drive the Mako in a circle around the area to where you can barely see the edge of the red line. You should find at least two elements/minerals on each planet that can be explored. There are rare things that will not show up on your map -- you will also have to drive around like this to find them. There are several more items than you are required to find, but it is good to go ahead and get them if you need the experience points. Also if you say the correct things to the Asari Consort, she will give you a trinket that will allow you to activate a Prothean Orb found on Eletania, or the "monkey" planet, in the Hercules system. It contains the memories of a Cro-Magnon that was observed by the Protheans. The orb will show up as an anomaly on your map, in the lower left corner.
When looking for certain items or armor, save before talking to merchant for first time. The merchandise is random. If you do not get anything you want, reload the game and talk to the merchant again. This trick can be used about three times whenever enough game time has elapsed for merchants to respawn new items.
Easy Mako Repairs
Use the following trick when your Mako is badly damaged and you do not want to or cannot spend Omni-gel to repair it. Save the game and reload it. You will find that the Mako is now totally repaired.
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.
Soldiers are combat specialists ideal for the front lines of a firefight. Soldiers begin the game trained with skills in both pistols and assault rifles, they have improved health and the ability to wear medium combat armor. As you progress through the game you can unlock assault training, skills with shotguns and sniper rifles, become able to perform first aid on yourself and party members, and wear heavy combat armor.
Engineers are tech specialists. Using the holographic OmniTool they can decrypt security systems, repair and/or modify technical equipment, disrupt enemy weapons or shields and heal their party. Even though they begin the game with only pistols and the OmniTool, engineers can unlock the ability to wear light armor and to reverse engineer enemy technology. They can also learn to put up protective shields and to heal the party.
Adepts are biotic specialists. Starting out equipped with pistols and light armor, the true strength of the adept is through the upgradeable implants that give them their biotic powers. These powers can be used to lift or throw objects, shield the party and disable or destroy enemies.
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.
Vanguards are biotic warriors. They combine offensive biotic abilities and weapons training to quickly take down opponents, and are especially deadly at short range. They can train with pistols and shotguns, and can learn to wear medium armor.
Sentinels combine biotic and tech abilities. Typically they use biotic abilities and advanced healing skills to defend allies, though they can also disrupt opponents with biotic or Tech attacks. They are more efficient at tech and biotics than other classes, but at the expense of combat. Sentinels can only use light armor, and receive no advanced weapon training.
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.
If you want to take the time, you can max out your Paragon and your Renegade stats without using any points. Once you get Spectre status, you can get up to four free points in each ability with each playthrough. Just play through the game three times and use the points you save elsewhere. The "Unlimited Paragon or Renegade" glitch helps.
Star Wars: Knights Of The Old Republic 2 Reference
Nihlus, the first Spectre you meet, is a reference to Darth Nihlus in Star Wars: Knights Of The Old Republic 2. They both have the same face paint.
Star Wars: Knights Of The Old Republic References
The rift station where you confront the Rachni is the same structure as the Selkath underwater base in Star Wars: Knights Of The Old Republic.
The Thorian race refers to the Ithorians from Star Wars: Knights Of The Old Republic.
"Scholarship" Achievement Codec Locations
This achievement requires that you locate information on all primary Alien: Council Races, Extinct Races, and Non-Council Races.
Aliens: Council Races
Easy "First Aid Specialist" Achievement
Asari: Speak with Captain Anderson after the first meeting with the council.
Salarians: Speak with Captain Anderson after the first meeting with the council.
Turians: In the beginning of the game if you miss it, you can get it by speaking to people about Specters and Saran. Otherwise, it should appear after your first encounter with Ashley.
Aliens: Extinct Races
Rachni: Speak with the VI Avina near the Consort Chambers/Krogran Statue about the Rachni wars.
Protheans: Speak with Captain Anderson and Nihlus on the Normandy at the beginning of the game in the Communications Room. This is your only chance in the game to get this codec. If you miss it, you will not be able to recover it later in the game.
Aliens: Non-Council Races
Batarians: After you become a Spectre, speak with Captain Anderson about his Spectre activities at the Docking Bay.
Elcor: Speak with the diplomat Calyn in the embassy. He is located at the end of the hallway to the right of the Embassy Clerk next to Udina's office.
Geth: While on the mission Eden Prime you will receive this codec automatically.
Hanar: Speak with the Hanar Shopkeeper at the Emporium.
Keepers: Speak with the VI Avina in the northwest part of the Presidium. She is very close to the Preaching Hanar and C-Sec Turian whom are arguing.

Quarians: Speak with Garrus in the medical center after fighting the thugs.
Volus: Talk to the VI Avina closest to the Embassy Clerk. You will get this by asking the VI why the Volus were the first race to get an embassy.
Find a planet that has a Hazard level 1. Stand outside the Mako and keep pressing [Y]. Make a note of how many times you pressed [Heal]. If you do not pay attention and run out of Medi-Gel, you could die from the Hazard level.
Easy Ally Achievements
Use the following trick to unlock all six ally achievements with only three playthroughs. When you start the game, focus on getting all six of your teammates. Choose two of them to play through the game with. Keep those two until you complete the majority of the game. You will get the ally achievement for the teammate you recruited first. After you get it, replace that teammate with another one as soon as possible. After the next assignment you complete, you will then unlock the ally achievement for the second teammate.
Easy Skill Achievements
The quickest way to gaining the skill achievements (Lift, Warp, Sabotage, etc.) is to stand outside the Mako and use it for a target. Do each skill with your current character 75 times and you will get the achievements for each one. However, two things must be noted. First, Neuroshock does damage to the Mako. When you see it begin smoking you must repair it. Second, AI Hacking does not apply at all here. You will need to actually hack 75 AIs or hack a few repeatedly before you must destroy them. The best way to get this one is to play the mission where you must go to the Earth's moon, or "Luna", and stop the AIs in the training facility. Save the game before you go into one of the bunkers and keep hacking them until you are finished, or reload and play again.
