De Bellis Multitudinis Version 2.0, softback miniatures rules, by Phil Barker and Richard Bodley Scott
Wargames Rules for Ancient and Medieval Battle 3000BC to 1500 AD
Description from boardgamegeek:
“A moderately abstract set of Ancient and Medieval miniatures rules. This ruleset is the bigger brother of De Bellis Antiquitatis. It covers the same time period (3000 BC – 1500 AD) through four volumes of army list books.
Armies are typically built to 300-500 points, and can encompass anywhere between 150 and 400 figures grouped onto individual elements.”
This copy includes an errata sheet upgrading the rules to version 2.1.
