ABOUT THE GAME

What you will find while exploring:
Fragments of the body and the past.

Trigaea is a post-apocalyptic science fiction interactive fiction RPG written by Adam Ipsen, aka RynGM. The central loop, as explained by the official, is to explore unknown lands, collect chips, and use those chips to unlock stories and physical enhancements. A 272,000 word branching story combined with RPG exploration and combat.

01

Connecting animals, machines, and alien life to the body

Genetic enhancement systems incorporate parts of non-human organisms and machines to adapt to harsh environments. Officially, the game is described as a combination of interactive fiction and RPG exploration and combat.

02

Choose a resolution other than defeating

In addition to combat, you can choose to resolve encounters through suppression, intimidation, or conversation. The choice of talking, subduing, scaring, or fighting will change depending on the opponent, and even with the same obstacle, the choice will lead to the story and how you use your body.

03

Connect 15 endings to 59 trophies and the next round

The 15 endings are recorded across games on a dedicated screen, and the bonus for each achieved ending is carried over to the next play. v1.2 also added 59 trophies and a New Game+ setting that allows you to choose how to transfer levels and enhancements.
