From the RPG description here on RPGGeek:
Mousquetaires de l'Ombre is a french RPG where players are members of a special order of musketeers fighting aliens.

In 1654, an Alien prison spaceship crashed in the Fontainebleau forest. Quickly Mazarin, with the help of the ship commander, created an order of special musketeers to bring back the prisoner and keep the aliens secret.

The game features a new dice splitting mechanic, a skill at d14 can be splitted in two hands, for attack and defense. For example, a player could split his d14 in d10 in defense and d4 in attack.
