From the 'This Quickstart PDF' section:
This PDF is just a taste of the full game. Still, the material in it will be enough to play a complete scenario of Coriolis — The Third Horizon.
PLAYER CHARACTERS
At the end of this PDF, you will find five complete premade player characters, complete with filled-in character sheets. The full Coriolis rulebook of course includes rules for creating your own characters.
RULES
After this introduction follow two chapters with the core rules for playing the game. Chapter 2 explains skills and Chapter 3 describes combat. The full Coriolis rulebook includes rules for talents, for equipment and last but not least, for ship design and space combat.
DICE
You decide what your PC does, but if your actions are especially risky, the GM will ask you for a dice roll to determine if you are successful or not. Coriolis uses only normal six-sided dice, but you might need a fair number of them. We recommend at least 10.
DARK FLOWERS
This quickstart PDF contains a complete scenario, called Dark Flowers. It is designed to introduce new players to the rules of the game as well as the Third Horizon game universe.
