It will have alot of gaps and a different gameplay if you dont play the other 2 ME.Taking the paragon path and doing all and i mean all missions will improve the gameplay in ME3.

in second part you need to shoot the tendrils that are conected to the main tendril,does Legion say "Shepard -Comander you must target vulnerable data strain to continue" ? (or somthing like that) if yes shoot other tendril that arent conected to the cluster but they have conection to the main ones,maybe you are missing one.

Yep pretty much.With the dlc the indoctrination theory is cleared out.

You can use a modified coalesced bin to modify the FOV but you need to keep the original one for MP,mod ones will be banned in MP.Otherwise idk i too have widescreen and i dont have any problems,try to update to 1.4 i think is the lastest patch version maybe helps.

Same floor as LIara Garrus when you exit the elevator on the left observation deck as u face the Memorial.She stands there after you recruit her.

Did you patched the game to 1.3? if not do it otherwise it wont work at all.OR maybe the dlc didnt installed corectly and some files dont work.

AS soon as it gets available,after Priority Palaven.It will gave you a new power dominate also the story why and what are the Reapers and who build them.Doesnt affect much the ending but still it looks average,not many consequences after you meet Leviathan,like he will enslave reaper armies including you or not.

WHat you wrote in this thread and the other 2 threads it is very usefull info for MP.Unfortunatly some good games appeared now (ex Borderlands 2 wich is way way way much better in CO op than ME3 MP) and ppl will start to forfeit ME3 MP.But is is nice that you made this detailed guide gj.

Answer to Q1:They where experimenting with the new reaper form as you saw in ME2 and they failed due to its destruction and because of that they forfeit the new reaper form and they stick to the original template,as HArbinger says in ME2:You have failed us we will find another way,Releasing control" so he is aware that human reaper is a failed experiment,humans where considerated genetical superior to other races (dunno why) and thats why they where building the supreme Reaper.Anothe answer could be that Leviathan doesnt know about the experiment cuz was destroyed before they where aware.

Q2:There where only 3 Leviathans and all 3 where needed to destroy a Reaper and they coudnt destroy the Whole Reaper armada only them.If you read the description of the Dominate power it is stated that after prolongued use the power becomes useless on the same subject,due to Reaper indoctrination.

Q3:They forfeit the power domination due to the bad reputation of humans cuz Shepard left the council to die and they where considerated an bad example and to avoid war they left the power domination.If you notice in ME2 other races are more hostile towards you if you killed the council and some wont cooperate withoug paragon or renegade action,if council lives there will be the oposite effect.

Q4:hmm the breeder will defenetly betray you and kill your soldiers and will create another rachni war.The queen will help you build the Crucible.That is the only bad and good thing so idk  perhaps is a big change in the ending without EC dlc but i dont see an meaningfull sense.

I hope i answered to your questions.If you have q post them :P

Q5:It was part of the original game.They ripped the content and made it dlc.I cant see the game without that DLC all of those stuff goes too well together.

Yes it is called ME2 and ME3 gibbed save editor and lets you to mod the savegames,idk if Me2 gibbes SE includes me1 or me3 Gibbed se includes both me1 and me 2 cuz i didnt used it but for sure this is the save editor.
