Dark Force Incursion is a game of war where you defend you people against a dark force that has infiltrated your land. It is a free Roll and Write game that is for one person, taking 20 to 40 minutes to play. You will need the rule book, one of the DFI maps, a six sided dice and a pencil. "Your land has been invaded by a powerful Dark Force. The speed of the invasion was frightening, and they have taken all the defensive forts in your land. In desperation you have gathered your dwindling army and now must push out to recapture these forts to secure the safety of your people and drive." —description from the designer
