From the introduction:
Vous êtes mort. Bon, jusqu' ici, ce n'est pas drôle, maise pas de panique: les portes du Paradis vous sont ouvertes. Votre mission, car vous l'acceptez (c'est ça ou 65 siecles de purgatoire...), consiste à devenir espion du Paradis, pour lutter contre les hideuses créatures de l'Enfer!
Enfer et Damnation! is a satyric roleplaying game published in Jeux & Stratégie (Issue NF 4 - Feb 1990)
The player characters are dead, but because of an angelic administrative error, they are sent to Heaven instead of going straight to Hell as punishment for their sins. Since they can't seriously be allowed inside, they're sent back to earth and recruited into saint Peter's secret service. Their mission, fight against the minions of the devil, foil their secret plans and maybe, if they prove competent enough and don't sin too much they'll be allowed to finally reach Heaven ("in a few thousand years, if you behave", as their superiors say).
The game rules are very light: characters have four stats, actions are resolved by rolling a number of six-sided dice equal to the stat and try to beat the difficulty number with at least one die, damage is handled using wound levels, and the player characters have a few "action replay" points they can expend to re-roll a failed test.
The game tone is quite tongue-in-cheek, even nonsensical at times (one the demonic monsters is a kind of giant bat that can disguise itself as an umbrella).
Interestingly, the game was published only a few months before Siroz Productions published In Nomine Satanis/Magna Veritas, a game with a similar theme which became one of the most popular French-created RPGs.
