Acquire the required number of groups based on the number of players. In this Deadhead Variant, resources are limited, and your Illuminati group's abilities are often all you have to work with. The timely play of a Special card can easily determine the victor. To play the Deadhead Variant, use 7 Special cards and all 39 deadheads. Special victory conditions are listed below.
Any number can play, but things really get bogged down with more than four players.
The makers of Illuminati knew they'd missed a few, and added blank cards so that we, who know where the true power lies, can add those missing groups. This group has the alignment of the group which controls it.
