This is a very amusing send up of Fortress America. Set in 2024, Fortress Illinois supposes a future in which Iowa, Missouri, Indiana, and Wisconsin invade Illinois. The game begins when Illinois destroys Gary, Indiana without warning. (Can you really blame them?) President Bobby Knight III leads the four states, which join forces and invade the Flatlanders in an effort to wipe out their leader, Governor Daley IV.

The game consists of a map and cards. It can not be played without owning Fortress America. This game was packed with and offered free with purchase Magic & Tactics' Axis & Allies homage, Middle East Combat.
