There was no Achievements Guide for this game. There's one now.

The planet names are taken from the in-game map, but it only follows your current path so you can't really use it to plan ahead. If you want a complete map, check this guide.

WARNING: some achievements (usually They 'Fell' and No Crew Left Behind) might not trigger correctly. If you don't get them at first (they'll appear in the game's Awards, but not on Steam), uninstall the game, delete everything in the Steam\steamapps\common\Starship Traveller folder, then reinstall the game and try again - although you'll lose all your previous achievements and found artwork in the game's Awards.

Classic Win
Complete the game in Classic Mode


Simply finish the game in Classic Mode. Your stats and crew don't matter as you can do it without fighting or even having to roll a single die. You only need to land on Cliba (to get the Prism), on Jolsen-3 (to get the coordinates for the blackhole) and on Terryal-6 (to get the Stardate).

Casual Win
Complete the game in Casual Mode


Finish the game in Casual Mode. Even easier than Classic Mode since you can rewind your decisions.

The Galaxy's Finest
Assemble your own crew for the first time


At the beginning of the game, select your own crew instead of picking the Admiral's premade one.

Artist
Find all the images hidden within Starship Traveller


Find all the full-page artwork. Use this guide for reference, it's pretty good.

Save The Cat!
Make it safely home with the ship's cat


You'll usually get this if you finish the game, since the only way to lose the cat is to leave it at the final Space Station.

They 'Fell'
Give a crew member an instant tan


On the Volcanic Planet, check out the volcano or scan for life signs and fail a Luck roll. You'll lose a party member.

Overindulgence
Slay all three Squinn to replace your ship's provisions


On the Jungle Planet, first set your phasers to kill the lone Squinn, then search for more meat and attack the next three with your bare hands. You'll want a good Skill and combat-proficient crew for this, since they have high Stamina.

The Science of Fists
Defeat the Manslayer Robot without asking for advice


On Malini, take part in the Contest and go straight to the Manslayer Robot without asking people around for hints. High Skill for both your crew and yourself are recommended once again.

RELEASE THE EAGLE!
Help an alien menace experience Ornithophobia


Lead Commander M'K Tel in your cargo hold and release your eagle on him (yes, you had one, even if there was no mention of it before, because every spaceship needs to carry random critters, and the Traveller is no exception).

In Two Minds
Defeat Dar-Villian guards while in a Dar-Villian's body


On Dar-Vil, don't bring your Science Officer, fail a Skill roll, then fail another Skill roll from the crew member of your choice to fight Dar-Villians. Using Free Choice in Casual Mode is recommended since you'll need good Skill to win the fight.

Dammit, Jim!
Attempt to cure a crew member with your own special 'treatment'


Get the Yellow Powder on the Barren Planet and try to feed it to the Ensign when he goes mad. He'll get killed but he's useless anyway.

Hostile Diplomacy
They shot first!


Open fire at Commander M'K Tel's ship as soon as possible.

Strict Discipline
Accidentally beat one of your own crew to death


After the Barren Planet, try to talk to the mad Ensign. He'll attack you. If you hit him 2 times, he'll drop dead. Since he has Skill 10, a high Skill is recommended as you can only fight for 2 rounds.

Do You Like My Hat?
Sport the latest in android based fashion


On Culematter, when captured by the PCs, try contacting your ship, then do it again when prompted to escape. You'll grab an android helm that gives +1 Skill. You can also get one by fighting the guard, but it's obviously harder.

Going Solo
It's just you and the ship now


Let your whole crew (except the Cat and the Ensign - only the staff with stats counts) die. The easiest way is to spam Phaser fights in Casual Mode (to try again if necessary) since they have a pretty high death rate. You can lose most of your crew on Cliba by being hostile to the natives, having your Medical Officer catch a mortal disease and getting into Phaser fights with the Rain Lord's guards. The Grey Planet can also kill up to 2 of your crewmen if you don't do the right things and are unlucky.

No Rain, No Pain
Have mercy on the Rain Lord's guards


Simply talk to the Rain Lord's guards on Cliba and surrender.

Table For One
Be Selfish.


On Macommon, choose to explore the city and when faced with an enemy, let Dilane die and beam back to your ship.

Stand Aside, Crew!
Insist upon being the one to attack an intruder


Let Commander M'K Tel aboard your ship, then try to subdue him yourself.

No Crew Left Behind
...except for that one time.


To enter the last Space Station, choose to give them part of your crew. Weirdly enough they'll usually want the cat. I guess deep space is kinda like the internet, cats are a serious business.

Surrender Is An Option
Aren't you the lionheart.


Let yourself be captured by the PCs on Culematter, then attack the guard. If one of your party members drops to 4 Stamina or less, you'll have the option to surrender. Pick your worst fighter as your first party member since the guard will focus his attacks on them.
