Companion Trophy in Journey
Finish the game with the same partner for the majority of the journey and return to the beginning.
How to unlock Companion
In order to unlock this trophy, you need to play at least the final two chapters (Snow and Sky) with the same partner, staying relatively close the entire time. There are benefits to touching each other, as it refills both your cape meters, in turn allowing more jump/hang time. You don't need to be touching for the entire chapters, but at least stay within a screen or two distance - the closer the better. The most important part is to complete each chapter at the same time (both of you should sit down in the glowing meditation circle at around the same time).
As some people want to do their own thing, or simply leave the game in middle, you might want to get a boosting partner for this. You can find boosting partners here.
"Glitch" warning: The PS3 trophy system can not unlock any trophies while you are syncing your trophies to Sony's servers. This applies to all games, as far as I know. As this trophy unlocks towards the end of the credits, some people have been syncing the trophies during this period, and unfortunately did not obtain Companion, Crossing and Rebirth as a result. Doing the requirements again, without syncing your trophies during credits next time, should unlock them.
The chapters are:
- Sunken City
- The Temple
After you complete the game, you can use chapter select at anytime, by pressing followed by .
