Hordes of the Things is a set of fast play fantasy miniature wargame rules designed by Phil Barker, Sue Laflin Barker and Richard Bodley Scott. These rules are based on the concepts of the popular De Bellis Antiquitatis (usually known as DBA) rule set.
On his website Phil Barker has made the HOTT rules available for free download. He writes:
Some time in 2009, these rules went out-of-print and the copyright reverted to the three authors. They are now unavailable from any supplier I have been able to find. I have consulted Phil and Richard and we are agreed that until it is possible to publish a new edition of HOTT, we will make it available at this website. Anyone who wishes to play HOTT, has our permission to download a single copy of HOTT version 2 for his/her personal use. (Also page 23, sorry for the omission. I'll redo the whole thing soon. )
The rules are available via the links above or go to Phil's site and click on the History of W.R.G. link at the top of the page. The HOTT rules are about half-way down the page. Don't forget to download the separate page 23.
I already own a published set of these rules and have a few Lord of the Rings-inspired 15mm armies in various stages of completion. This is a rules set that I've read and admire and I intend on playing in the future. I don't know when I'll get around to playing but it's definitely on my 'to do' list.
Check them out.
