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.
