In this guide, I’ve listed all the hidden technologies in Star Trek: Voyager – Across the Unknown, including how I unlocked each one, their locations, categories, and all sector details.
Unlock Hidden Technologies
At the beginning of the game, I see 45 unknown technologies in the tech tree.
Table of Contents
They appear as question marks and are divided into the following categories:
- 8 Engineering Tech
- 8 Crew Tech
- 14 Science Tech
- 10 Combat Tech
- 5 Borg Tech
To find hidden technologies, I carefully explore the sector map and check every Point of Interest. If a location contains something unique, its title appears in gold and references an episode from the Voyager series. Sometimes a required Point of Interest does not spawn. When that happens, I restart the sector and reload to try again.
I also obtain hidden technologies through certain Side Missions and Main Missions.
