Dark Heresy
Fantasy Flight Games/Games Workshop
Dystopia/Dark Science Fantasy/Investigative Horror
You are an acolyte in the Holy Inquisition of the Emperor of Mankind. Which this being the 40K universe means you're the low-man in the pecking order, which also means that chances are you're going to die. Horribly. Then your replacements are going to die horribly. How horribly? Well check out the 16 tables for rolling critical injuries.
In all seriousness, you are the field agents for an Inquisitor, charged with investigating conspiracies against Humanity and ensuring they don't come to fruition. Characters could come from a variety of homeworlds and backgrounds, each giving their own unique bonuses, as well as superficial quirks to make them pop more. In the second edition classes were done away with for Archetypes, opening up more varied characters (for example, an Outsider Archetype could be an outlaw, a scavenger or a bounty hunter, just off the top of my head). Likewise, every archetype could do something useful, encouraging players to try different things and encouraging GMs to run games that aren't gun-n'-run.
This is a game that will ensure that no character will get out of a campaign unscathed, be it injury to the body or the mind. This is a game with a corruption and insanity mechanic, because your character will be staring into the abyss and it will stare back and it will leave its mark on them (that said, an extra hand bursting out of their chest is pretty handy....for about five minutes before their former comrades put them to the torch...)
Pros
- Not your typical RP, there is an emphasis on investigations, uncovering clues and determining where the group should go next.
- You are forced to plan ahead. Use cover, make plans. You can't go charging into every combat, because you will get maimed.
- Choices, you have so much freedom when creating your characters. Career paths can open and veer off, leaving you with a unique group if you want.
- A variety of locations. Because this is the 40K universe, there is literally a million worlds open to you, ranging from sparsely populated desert worlds, to hive worlds with billions of people. And each is unique in its own way.
Cons
- It lethal. Dark Heresy and the other Games Workshop RPs have a well deserved reputation for how dangerous combat is. Starting characters have somewhere between 9 and 14 wounds and the average rifle type weapon does 1d10+3 damage on a hit, meaning if you're unlucky, you could be killed in one round. Added to this, there is one form of resurrection and its not the kind you want to inflict on someone.
- Tiered gameplay. Because Dark Heresy was the first 40K RP, it hasn't done that well in matching up in crossovers with the later games. As such, a high level DH character might have the same power level as a beginner character in the next game, Rogue Trader.
Sadly, due to the ending of the partnership between Games Workshop and Fantasy Flight Games earlier this year, Dark Heresy and the rest of the RPs are now out of print. Meaning the only way to get the books is secondhand.
