The Wasatch Front Historical Gaming Society offers a new colonial campaign: The Return Of The False Prophet of the San Juans.
From the description:
This is a fictional Sudan campaign in tribute to the Washington Wargamers and Lynn Bodin who had a fascinating campaign during The Courier’s Sudan theme. All of the players are on the Anglo-Egyptian side and the campaign is card driven, which produces a lot of chaos and uncertainty in planning. The campaign features the initial rebellion, cards for the Hicks expedition, the arrival of Gordon, Graham’s forces, and finally Kitchener and the Re-Conquest. The PDF contains the rules, cards, counters, and a planning map, plus you can dowload the full sized map below.
