A game of 'Hordes of the Things' need not be limited to a straight one-to-one battle as described in the rules. Here are some scenarios and campaigns which take the game further:
Scenario for the battle of Pellenor Fields from 'The Lord of the Rings'. This scenario is based on one in Miniature Wargames, which had its own rules. I have modified it for HOTT. It is still unfinished, but is presented here for comment and criticism.
Nick Grant has a page on using 20mm plastic figures to fight a Hyborian campaign. This uses the lists from the rules.
The Great Battle - The last stand of the Air Demons, a large scenario by Dave Cinabro.
Bretwalda! - A campaign set in a post Arthurian Britain, by Charles Turnitsa and the Old Dominion Military Society.
Desert Saga - Can Thor Nogson rescue King Rashid in the Land of the Silver Sand? Find out in this scenario inspired by the sagas of Noggin the Nog and written by Paul Grace.
None Shall Pass - An outnumbered force attempts to hold a vital pass against a superior enemy. Can it hold out until the reinforcements arrive, and just what is that dust cloud in their rear? Scenario by Alan Saunders.
Caer Cadarn. An Arthurian Battle from Bernard Cornwell's 'Winter King', by Adrian Delves.
