Once you beat the main story, you can start a new game that puts you back near the start of Starfield with new story permutations, new dialogue options, and even at least one new main mission to complete. And get lucky is exactly what happened to X/Twitter user and Starfield superfan @NikoMueller, who after travelling through 34 multiverses (33 New Game Plus runs) finally decided to “settle down”. But… surprise! Awaiting the silent protagonist at Constellation HQ was a fully voiced version of the player character herself.
If you encounter this New Game Plus variation you’ll get to see some fun interactions between the player character and their multiverse self, as well as other main characters in the game. According to NikoMueller, the alternate version of their character has the same stats as they did from their first playthrough, and has plenty of questions herself. Well you would if another version of you just walked through the door, wouldn't you? (No, it does not appear to be possible to romance yourself.)
So, what’s going on here? As you arrive at the The Lodge in this variation you find a version of you already exists in this universe. You'll be able to talk to yourself and explain that you're Starborn and what you know about the Artifacts. While the you that's currently in this universe doesn't really want to help out, you can convince them to team up with you and recruit yourself.
