Twilight World: The Game

Twilight World is a set of free wargames rules for miniatures games set in a post-apocalyptic, zombie future. The author writes:

Until now, they have only existed in our imaginations. “When there’s no more room in Hell, the dead will walk the earth.” Now humanity must fight for its fragile existence, and the right to survive in a Land filled with the unliving.

Description
Twilight World is a basic game system that was designed for quick and easy miniature wargaming in a modern horror setting. These rules allow players to fight desperate battles with small groups of human survivors (heroes) in low intensity battles, primarily against other players who control zombie hordes, and roving gangs of villains… and worse.

These rules are designed to play on a table top using 28mm miniatures. Movement and firing distances are made using a 1”squared game board, although there is no reason why you can’t play on a hex board, or simply measure distances in one inch increments as you go. However, by default these rules assume the you will be using a squared game board. The rules also require the use of up to four 6-sided dice.

A battlefield usually consists of some 3D terrain pieces. These represent obstacles such as walls, buildings, deserted vehicles, raised roads, rivers, bridges, trees, etc, etc. All this can all be made from scratch with relative ease by even the most frugal modeler… or are commercially available from many shops and on line resources.

DayZ Zombie Wargame/RPG Rules

Day Z is a set of campaign wargame and RPG skirmish rules for games set in a zombie apocalypse. The author writes:

This DayZ ruleset is played on a simple grid map, with each grid square representing an area fifty meters on each side. The majority of towns and rural areas can be represented by a twelve-by-twelve map, though some larger areas such as Chernogorsk, Elektrozavodsk, and Solnichniy are better-suited by a double-wide, twelve-by-twenty-four map. The game starts out on the coast of Chernarus, a former Soviet republic currently experiencing a virulent outbreak of a plague rumored to originate from an island offshore of Taviana. The plague does not appear curable, and causes symptoms in its victims similar to ‘zombies’ described in popular media. Its extents are currently unknown, but it is believed to have spread across much of Europe and the Middle East.
