Mass Effect

If you want to have an easier time shooting and killing fast-moving enemies such as Geth Hoppers, Geth Drones, and the like, try the following. Open up the command wheel when engaging them in combat. This will freeze the game, but you’ll still be able to aim your gun at foes all the while. Aim at the fast-moving enemy and then get out of the command wheel. This will score you direct hit after (admittedly cheap) direct hit.

In Quasar, bet Y on odd and X on even.

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.

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.

When you are on the mission about the missing Marines you will encounter a large worm creature. To defeat it, jump just before the projectile acid the worm spits. Meanwhile, attack it with missiles (RB) and constant gunfire (RT) and it will soon fall.

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.

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.There is also a subplot for romance where you must choose who you want to have a relation with. You may lose the gamerpoints if you do not talk to the crew.

In the ExoGeni facility there are several claws that feed power that must be terminated to continue the mission. You will come across a control panel for the Shuttle Bay Door Controls. This panel has 5 switches of different pressures:

(5 PSI Valve) (7 PSI Valve) (17 PSI Valve) (11 PSI Valve) (13 PSI Valve)

The objective is to add just enough pressure to fill the gauge between the two arrows. Too much will reset the puzzle and you will have to play with different combinations. Once a correct pressure is reached the bar will turn yellow and text under it will read "WARNING, HIGH PRESSURE". Enter 7, 11, and 13, then activate. This will create enough pressure to break the claw and deactivate the Geth power being flushed into ExoGeni.

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.
