Everyone knows there are there endings: destruction/ control/ synthesis. But there is another one (which is worse than the destruction one). If you turn round and shoot the catalyst (the little boy) then the cycle continues and everyone dies.

When visiting Ashley at the bar after your drinking game a Batarian will come up and say "My friend doesn't like alliance types", then continues to say "I don't like them either" which is a reference from when Han Solo was in the bar and disturbed by Greedo.

Ok this concept works best if you have two people on your team with incinerate power like Edi for example or you have the class Infiltrator. Make sure you have the most damage for the ability on both characters and make sure you and your team has the Carnifrex or the Pallidan heavy pistol (comes in handy once both are at highest level upgrade). Target the brute you use both powers and shoot at the brute with the graveyard pistols and ammo enhancements. Also like incendiary or Cryo will work. If done quickly enough you will kill a brute in 2 seconds.

During the introduction sequence for the mission where you are about to land on Rannoch, Commander Shepard is standing in the Normandy's bridge talking to Joker about the fact that there sure a lot of enemies out there. Joker laughs it off and says that with the Normandy's stealth drive engaged, the only way for the Geth to notice you is if you all start singing the Russian national anthem. This is a direct reference to the 1990 film, The Hunt For Red October.

At the beginning of the game, when you are fleeing Earth, you can see the child you will eventually talk to running away from Husks. Before you get to the part where you see Husks climbing up the wall (the first time you shoot at something), you can see the boy looking below, looking over the railing. When the Husks arrive and Anderson coaxes you to shoot them, continue to observe the boy run into the building and lock the door. The building is blown up seconds later, but he apparently survives in the vent.

Note: A Kinect is required for this trick. In London on Earth, Harbinger shoots his laser and knocks everyone running to the teleporter that is on the ground linked to the Citadel. You will get up and continue to walk in slow motion to the teleporter armed only with a pistol with unlimited ammunition. You normally cannot use your powers with LB or RB. However, if you have a Kinect you can voice commands such as "Carnage", "Warp", "Singularity", or any other projectile power. Shepard will use the power while in the slow motion state.

Upgrade nova all the way so it does the most damage. Next fully upgrade biotic charge so it restores all shields and has a short cool down. Keeping your cool down rate around 200 using this setup allows you to biotic then nova and have your cool down end instantly.

First you must have an imported game from ME2 and must have a military strength between at least 3700 and maximum. Get to the end with enough goods and persuade him to kill himself (hilarious). Then proceed as planned in the game and when you speak to the catalyst choose all left side inquiries until there are none left. Then choose preferred right side choices and the catalyst will eventually say there is another way. Go for the positives reaction after and he will tell of a third way. Then choose your preferred path. The beam, the machine or the controller.

Progress through the game until the part where Shepard visits an archive of ancient artifacts . Look carefully at the Earth Archives to see the Ark of the Covenant from Raiders Of The Lost Ark. Note: There is also a bowl of Easter Eggs on a desk in this area.
