Miniatures Rules
La guerre des ames (souls war)
Souls War is a French language set of rules where angels and demons battle for the souls of humanity. You can use the Google Translate function in your web browser to get an English version if that’s what you need. Here are the first two sections of the rules:
0-1 Hardware
A heaven, a hell, a purgatory populated by angels, demons and wandering souls. The figures can be of any brand (as long as the scale is respected), your monsters can serve as demons (and yes tyranids often populate the nightmares of marine spaces) and any humanoid figure can serve as soul. Some Orcs believe in god, well that’s what is said in some club like the Crazy Orc. For the angels
0-2 Goal of the game
The purpose of this merciless struggle is to harvest souls either for heaven or for hell. With three players, humanity tries to reincarnate in order to return to earth.
Point of No Return Starship Rules
Point of No Return is a set of free wargames rules for starship combat with simple vector movement and inertia.
Task Force Zeta Starship Rules
Task Force Zeta is a set of free wargames rules for starship combat.
Pundits will tell you that representing space combat in 3 dimensions is a wasted exercise in mathematics, and that two ships fighting can be equally well represented on a 2-dimensional plane. What happens when you have three ships? ten? Did their captains all just conveniently forget about attacking/defending from the z axis?
Task Force Zeta allows you to fight battles against opponents in a representation of real (3-D) space using vector movement – without doing complex math every time you move or fire. Fourteen different ship classes are provided, along with fighters and bases, as well as basic rules for ship construction – design your own factions or convert ships from your favorite movies/TV shows!
