Index -> Playing the Game -> Card Types -> Mission
Mission cards represent the places your characters travel to through the Stargate. They will need to use one of the four skills to complete each mission. You'll often need two or more characters, working together, to succeed in meeting a mission's requirements.
In each game, you will have exactly 12 missions.
The experience on a mission is one of the ways you can win the game. The glyph is earned by one of the characters who successfully completes it, sometimes increasing his abilities. There are six different glyphs:
Gemini
Libra
Orion
Pisces
Scorpius
Triangulum
