Walkthrough: How to Get All 15 Endings in Trigaea (SPOILERS!)


Hi all, and thanks for playing Trigaea! This is a walkthrough on how to achieve the fifteen different endings in Trigaea (excluding obvious “Bad Endings”).

I strongly recommend playing through and trying to obtain each ending organically, as you’ll enjoy the game more this way! Some things are impossible not to spoil if you provide a walkthrough, even in dot point form - this guide is intended for the truly lost.

Still here? Okay! Here’s how to get all the endings. I won’t cover how to win the fights in this guide, but this may be something I do in a future update if there’s demand for it.

And it’s needless to say, but I’m going to say it anyway: spoilers ahead!

The Endings You Can Get

While there are fifteen different endings, they are grouped together like this.

  • Ending 1: Refusing to take any action
  • Endings 2, 3 & 4: Siding with the x’irii
  • Endings 5 & 6: Siding with the machines
  • Endings 7 & 8: Siding with humanity
  • Ending 9: Siding with humanity, then switching sides to the machines
  • Endings 10, 11-1 to 11-4, 12: Neutral endings

There are also a ton of bad endings (Bad Endings A to H) throughout the game. I don’t count these among the 15, as these are pretty brief, and the game doesn’t keep track. But if you want to see every one, maybe I’ll make a list (and an achievement) for getting these one day. :)

Before T’yani Grove

The “point of no return” in Trigaea is before you head to T’yani Grove. This is immediately after you get Main Memory 7 and learn how you lost your memories (as well as who was responsible).

If you don’t even know what T’yani Grove is, then you haven’t reached this point, and you’re reading this guide too soon! 

You don’t need to save before you go to T’yani. The game will offer you the ability to go back to this point of no return after you finish the game via the New Game+ feature. I mean, I would personally save, because I’m a compulsive saver, even when it’s not logical.

That said, you can certainly die and hit a “Bad End” when heading to the final area - the Northern Wastes - so I will point out where to save in the guide below.

To head to T’yani grove, you need to head to Shi’ari grove. If you saved the twins from the walker, they will be waiting there for you. If not, the war band (S’ven, Celcha and Y’rela) will be here instead.

How to Get Each Ending in Trigaea

Ending 1: Sealed Senses

  • Visit Shi’ari Grove.
  • When prompted, agree to go to T’yani grove.
  • When you meet the Ru’ul, shoot them either upfront, or hear them out and then refuse to join them. Either will get you where you need to go.
  • Act however you want to get out of the situation (Fight, Run, Talk).
  • You should return to Main Camp after this point.
  • Head to Sector 54.
  • For the first response to Gabriel, answer any way you want.
  • For the second response to Gabriel, refuse to help them with their plans.
  • You’ll be back at Main Camp after this point.
  • Head to the Forest Ruins to meet Shay.
  • Refuse to help Shay.
  • When you return to camp, tell Esra “I just don’t want any part of it.” Then, answer “Yes - I don’t want to get involved.”

Congratulations! You’ve got the easiest ending in Trigaea, and the only one without any fighting.
