The game is about a character with voices in his or her head. The focus of play is the battle for control over the character”s body, the battle to decide what the character’s beliefs and behaviour ought to be.
One player is the main or Primary personality, while the others, the Insurgents, will persuade, cajole and threaten their way to dominance over the Primary. The system provides backing to their threats; the Primary can only resist for so long before the Insurgents explosively take over and force their agenda.
There’s an optional alternative where you play a group with warring factions, but the principle is the same.
The Enemy Within is free to download along with the other games on the free games tab.
