This is a work-in-progress walkthrough covering Main Missions, Side Missions, and Away Missions, including the choices tied to them and the rewards tied to those choices.
Right now this document covers roughly 60% of decisions up through Chapter 6. Formatting will get cleaned up later — for now, you’re getting raw numbers and direct data.
All values listed are for Normal difficulty.
Star Trek Voyager Across the Unknown Main, Side Mission Guide
Away Missions are formatted like this:
Mission Name
Skill Required – Threshold – Reward
If a line has no reward listed, that option does not provide one.
Example format:
Mission Name
SkillA 42 +30 Duranium
SkillB 40 +16 Duranium +16 Tritanium +16 Science
SkillC 58
Later entries use shorthand for resources:
- U = Duranium
- T = Tritanium
- S = Science
- M = Morale
- F = Food
- D = Deuterium
- I = Dilithium
- C = Crew
Basic Tips
Use heroes actively. Mess Hall and Hydroponics Bays are extremely helpful. Mess Hall boosts Morale, Hydroponics speeds food production. Both reduce long-term pressure.
Combat focus: I lean heavily into phasers. Early game, Tuvok, Paris, and B’Elanna provide strong DPS, shield regen, and survivability. Later I replaced B’Elanna with The Doctor and found overall damage taken was lower.
Crew management matters. I’m in Chapter 6 with ~50 excess crew. Extra crew increases food and housing drain. Be selective.
Sector Morale penalty caps at -30 (Normal). This is manageable. It gives you breathing room to focus on science research.
Chapter 1
Tutorial. No meaningful branching choices observed.
General Advice: Pick Chakotay over B’Elanna.
