Choose an ending, then replay the final checkpoint
Choose Stabilise Rift Zero for Dawn of Tomorrow, or Close Rift Zero for Tomorrow May Never Come. After completing either ending, open Change → Start New Journey and have the host select 7-5 The Fate of Two Worlds to return for the opposite choice.
What each Rift Zero choice does
| Choice | Outcome and achievement |
|---|---|
| Stabilise Rift Zero | Saves Earth at the expense of the world beyond the Rift. Awards Dawn of Tomorrow. |
| Close Rift Zero | Preserves the world beyond the Rift while Earth's energy crisis continues. Awards Tomorrow May Never Come. |
Agree on the outcome before committing
At the Theta Splice machine, separate chains control stabilizing and closing the Rift. Agree with your partner on the option you want before pulling a chain. Use the option's name when coordinating so you both know which ending you're about to confirm.
Your Rift Zero choice is independent of the earlier laboratory puzzles. Closing and stabilizing are alternative endings, so you do not perform them consecutively during the same conclusion. Finish your chosen ending, then return through chapter selection for the alternative.
Finalize your chosen ending together
- Pull the Theta Splice chain for your intended outcome: Stabilise Rift Zero for Dawn of Tomorrow, or Close Rift Zero for Tomorrow May Never Come.
- Press your console confirmation button together with your partner's button to register the confirmation for the selected outcome.
- Repeat the synchronized confirmation until you have completed it three times in total; this finalizes the selected ending.
Replay the final choice for the other ending
- Open Change → Start New Journey after completing your ending to access the checkpoint replay setup.
- Have the host choose the unlocked 7-5 The Fate of Two Worlds checkpoint, returning you to the final stage without repeating the complete campaign.
- Pull the opposite chain: select Close Rift Zero if you previously stabilized it, or Stabilise Rift Zero if you previously closed it.
- Complete the console confirmation together three times to finalize the alternative ending and obtain its corresponding achievement.
What happens if the decision timer expires
The decision has a 10-minute timer. If it expires, the selected needle position determines the outcome; if neither side was selected, the game may choose randomly. To get the ending you intend, select its chain and finish the synchronized confirmations before time runs out.
Remember the collectible tally when replaying
Starting a new Journey begins a fresh collectible tally. Keep that in mind if you're also pursuing collectibles when you set up your ending replay. Plan that collection separately from the short return to the final choice.
