ME:A Ending Thread (EXTREME SPOILERS)

- Your sibling gets captured by the Archon (you get to play as them for a few minutes). And SAM. Your sibling actually saves your life by stabilizing the link between you and SAM and gets captured by the Archon on the Hyperion that way.
- You realize you can use Remnant tech without SAM, and use your connection to awaken an entire Remnant army.
- You use that army to face the Archon's, along with your allies that you've made throughout the game.
- You infiltrate Meridian (which is actually a planet, from what I was able to tell - I might be wrong), and go after the Archon.
- The planet is all covered in a Remnant sphere.
- The planet is beautiful (and end up becoming the new home for humanity at the end).
- You enter a final vault (or whatever that is).
- The Archon is able to interface with Meridian using your sibling's connection and SAM. He tries to use it to destroy all planets in the cluster (because the tech can actually do that). It can also give them a habitable status.
- Everyone joins up for the final push, including the squadmates you didn't choose to be in the squad.
- The Hyperion crash lands and the Captain (Dunn, if I recall her name correctly), dies.
- You don't face the Archon in the end, but actually a metallic thresher maw (like the one we've seen in the trailers), the objective is not to defeat it, but disconnect the Archon from Meridian, going around the room activating specific points. You are able to do that with the help of your sibling and SAM.
- Archon gets disconnected and dies electrocuted (or not, it isn't very clear, he just lies there on the ground).
- You get out of the vault with your squad and everyone comes to praise you for saving the Initiative (including the Salarian pathfinder [if she still lives from a decision you get to make earlier in the game]).
- Roll credits
- Middle credits scene - Another Kett appears looking at Meridian (similar to Shepard's scene in the teaser trailer for ME3).
- After credits - your sibling awakens in your father's quarters and you get to talk to them a little more.
- The leaders of the Initiative want your opinion on who should be the ambassador for the Initiative in the Cluster. You have four options:
The angara, Moshae - Outpost leader, Bradley - Salarian pathfinder Raeka (if she still lives) - Krogan Nakmor Kesh of the Ai
- They mention that the ambassador will be temporary as they want to elect a new Council after.

Reminding that things might be different depending on the choices in the game, but that's what I've seen.

I'm hot for both the salarian pathfinder and Nakmor Kesh, so I'm gonna have a hard time picking. BD

If it had ended up like the ME3 ending, I would have definitely cancelled my pre-order (especially combined with the terrible CC and only having 2 romance options). Rather sick of having the hero die in the end unless you pull a major 'evil'/renegade move. Thank bob for MEHEM.
