Rifts: Fallout rules

(image above by Bethesda Softworks)


So, I will make no secret of the fact that I am a rabid Fallout fan. I absolutely love the setting, with its madcap humour, its retro-60’s aesthetic juxtaposed with a horrible post-apocalyptic hellscape, and with its emphasis on narrative storytelling and open-world freedom.  Fallouts 3, and New Vegas remain some of my favourite RPGs ever, and it has always bothered me that there isn’t a dedicated, pen and paper Fallout RPG system– that is, except for an old GURPS module that is now out of print. Despite the fact that Fallout: Wasteland Warfare is in the works as a minis game, and despite Fantasy Flight’s recent Fallout board game, there seems to be no news of a Fallout RPG system in the works, much to my sadness.

A little more than a year ago, I undertook what was probably one of the most ambitious RPG undertakings I had ever done: I tried to run a Rifts campaign set in the Fallout universe. I went with Rifts, firstly, because it was a system that a lot of people in my usual RPG group were quite familiar with, and secondly, because Rifts and Fallout share many similarities: both are set in a post-apocalyptic world, full of monsters and horrors, where new nations have been carved out of the bones of the old. Power armour, giant robots, mutants, and even aliens are replete in both universes, although Rifts goes slightly heavier into things like dimension-hopping, aliens, and the aforementioned giant robots (Fallout, sadly, can only boast Liberty Prime in the giant robo department). Because of these similarities, Rifts seemed like a natural fit…although it would need some tweaking.

My campaign itself was set in post-apocalyptic Canada, and was going to span a long journey from the Rouge Valley east of Toronto, to the crumbling ruins of Toronto itself and several of its landmarks (including the Toronto Islands, historic Fort York, and a certain, extremely tall tower). Sadly, the campaign quickly fell apart due to a variety of factors…though that is a sad story for another time, though suffice to say it was a very stressful period of my life. What I do want to share today, however, is the one thing I am still proud of from that campaign: the house rules I had set up. I wanted the campaign to be more than just Rifts rules with a Fallout skin on top: I wanted the rules to reflect the equipment, creatures, and even unique gameplay mechanics of the world without going too much overboard.

In the end, I wound up adding some skills, removing some others, removing more than a few classes that just didn’t fit into the Fallout universe (like psychics, for example), and, most importantly of all, creating new rules for things like perks, radiation, and chems. Hopefully, if anyone else out there plays Rifts and wants to have their try at a Fallout campaign, these rules will come in handy– though nothing is stopping you from making any amendments of your own, especially if you are using Rifts or a d100 percentile system similar to rifts.

Before all else, though, I want to thank my player party at the time, and particularly my friend Andy, for helping me develop these rules, especially since my knowledge of Rifts was quite poor at the time.

NOTE: these rules are not in any way official, nor in any way endorsed by Bethesda Softworks or Palladium Books. Furthermore, they have been created purely on a non-profit basis.

Each time a player fails a hacking roll, the difficulty is increased by 10%.
-Assuming your first hack is at -0%
-A failed attempt gives a -10% to the next roll, cumulative to future attempts
-A player with a 40% chance of success, who has failed one hacking attempt would need to roll a 30% or less to succeed. A second failed attempt would result in a -20%, or a roll of 20% or less.
-A player who reduces their chances to pass a hacking skill check to 0% or less locks that terminal. (This includes other players)


Radiation works as follows:
Every time a person is near a source of radiation, they take a number of rads per melee round. The longer they stay near the radiation source, the more rads they take. Some sources give off more radiation than others, or give increasing amounts of radiation the closer the character is to it.
Classifications of radiation sources are as follows:
-Minor- 5 rads/second
-Medium- 10 rads/second
-Dangerous- 15 rads/second
-Severe- 20 rads/second
-Catastrophic- 25+ rads/second

As characters take more and more rads, the following effects will apply:
-At 200 rads, -2 to all stats, -1 to combat rolls
-At 400 rads, -4 to all stats, -2 to combat rolls
-At rads, -6 to all stats, -3 to combat rolls
-At 800 rads, -8 to all stats, -4 to combat rolls

1000 rads is considered to be a lethal amount of radiation. Once a character reaches 1000 rads, they will immediately die.
Radiation can be reduced by taking Rad-X or Rad-Away, or, if one is available, going into a decontamination chamber. Some doctors in the wasteland have developed herbal or home-made counters to radiation as well.
