[ EU ] There is a secret alternate ending to one of your favorite video games that is extremely difficult to get . Tell me the story of how to get it , what it is , and how it effects the game . ( Possible spoilers ahead )

It's entirely possible to find a secret scene in the game Mass Effect 3 known as the Angel Ending. To get this ending, you must trigger the secret event flags in all 3 games, as well as have both iOS games plus the Codex app ( if you have Infiltrator on Android, it counts despite not having the other games on the system ) tied to your Origin account. To get this ending: 
 
 1. Have no romance in any game. 
 2. Play as Adept Fem! Shep. 
 3. Have either Neutral Alignment or anything except perfect Reputations. Must be > 40 % for both Paragon and Renegade, must be < 80 % for both. 
 4. Complete all Assignments. 
 5. If you complete all DLC content, ignore either rule 3 or 4. Else, you'll get a bonus exp multiplier off the bat. 
 6. Unlock all gear in Infiltrator. 
 
 When all these requirements are met, you'll get the choice to unlock this extra ending. Select'You do n't know anything!'

'You have no idea about anything related to organics *or* synthetics. You're so ignorant...' 
 
'And you know more than us?' the Catalyst asked.'We are endless... we are eternal.' 
 
'You're pretending to be a small boy to guilt-trip me into an ending that I clearly do n't want!' Shepard yelled in annoyance.'If you chose either [ Kaiden/Ashley ] or any of my friends as well, maybe it'd work. Do n't you clearly see how terrible you are? Dear God... maybe if you actually tried something other than'Kill everything', then things would be different!' 
 
'There are horrors out there that you'd wish you'd never know about,' the Catalyst sneered. 
 
'I can take it,' Shepard replied with confidence. 
 
'Oh, can you?' the Catalyst answered. 
 
 The Reaper force began to suddenly stop its attack while the Catalyst let out a pulse which knocked Shepard to the ground. Feeling her arm seer in pain, she gripped it to try and ease the burning sensation as the Catalyst began to re-calibrate it's own programming. Then... a star-map appeared above her while the Catalyst shut down, signalling to one world in particular. 
 
'If you believe yourself ready to take on these horrors, go to this world. But know this - while the Reapers will no longer aim for salvation through destruction... they will *not* aid you against this foe.' 
 
 -- - 
 It's been 5 years since that day. She headed to this world alone, only saying to her friends that she had something to do. Dressing inconspicuously, ever since that... pulse, had changer her body shape. The markings on her arms tended to glow when she got excited, but she knew the answers had something to do with this world. 
 
'Hey, an easy target,' a marauder said as he held his gun to her face.'Maybe she's got quite a few creds on her.' 
 
'Sorry, I'm broke,' she said. She did n't even try and pretend to be in danger, even if she was only armed with a single pistol.'Now, get that gun out of my face before I'm forced to do something stupid.' 
 
'Oh, what are you going to do? Cry?' 
 
 She just gave a quick smile before, with a pulse, she faded out of reality, to the shock of the bandits targetting her.'... the fuck?' 
 
 Then, she reappeared behind the man who had threatened her. The men under his command were now on fire, running away or dead. Shepard still did n't have her gun drawn and the man who was holding her up was now frozen in shock at this impossible feat - not even a biotic could do that! She just gave a curt smile as she parted the hair in her face. 
 
'Sup?' was Shepard's only reply. Or, as she was now known on the border world of Pandora...
