From the description:
ORBITAL is a game about a neutral space station, cut off from a conflict that rages among the stars.
Players choose from six customisable character roles and setting elements on the station, then play to find out how their community is shaped by their decisions.
This supplement, Mind Games, expands the available character roles. It also includes a short, standalone bonus game that may help players build up some minor NPCs for the setting elements 'the station itself' or 'the unaffiliated'.
Included in the supplement are two new character playbooks that require a copy of ORBITAL to use:
- The Scholar: An enigmatic individual, consumed by their work but willing to mentor other keen minds.
- The Maverick: An independent individual, living a nomadic life but somehow drawn to the station.
Mind Games also includes a short, light-hearted bonus game:
- Simply The Pest: a standalone two-player game depicting a futile duel between the station's long-suffering exterminator and some tenacious pests.
Players roll six-sided dice to determine their character's names, characteristics and equipment. Then, using a tic-tac-toe board, players take turns making moves and answering a prompt question. Win, lose or (probably) draw, there is a final question to answer.
