Nechronica
Ever wanted to play a horror game where the player characters are cyborg zombie lolis with horrendous body mutations/mutilations? You sick fuck Now you can! From the creator of Maid RPG and Zettai Reido, Nechronica -The Long Long Sequel- puts the players in a world where humanity and everything else is dead, except not quite dead, which allows for all kinds of body horrors to fool around and terrify lesser body horrors. It uses a single d10 for normal checks, plus or minus any modifiers, with a final result of 6 or more being a success, and d100 for a bunch of tables, mostly related to character creation. Interestingly, the GM is literally the Big Bad.
Setting and some History
The game takes place in a post-apocalyptic cyberpunk world (ours!), which came from a nuclear war, followed by dwindling resources and wars for control of them. Enter the incredible powers of necromancy, which comes from pure science, thanks to the magic of slime mold based nanotechnology. A nuclear war erupts in South America by the end of the 21st century and gets the whole world on their toes. While nuclear weapons were effectively banned in the middle of the 22nd century, the wars saw wide use of undead, as the slime mold needs very little nutrition to make its host body work, which meant you could keep a full, working and capable standing army on little more than a single bottle of vodka and one cigarette. As a bonus, you could get all those dead corpses that were doing nothing being dead and put them to good use! After a while, it also became possible for personalities to be downloaded and uploaded into the slime mold, effectively creating an "artificial immortality", also all kinds of problems with memory alteration. Wars see the use of all kinds of exotic weapons, such as insects, virus bombs, earthquakers, etc. After someone "accidentally" starts and ends the final nuclear war, humanity is essentially wiped out. Necromancers then fight among themselves and, realizing they are literally fighting for control of shit they don't even want to think about, retire to their own domains.
The year is 2200, Earth is a pretty shitty place with zero saving graces. No history, no culture, no cities, no new nothing. Thus begins the sequel of history.
GM as the BBEG
It's no coincidence that the GM is called Necromancer here. The game states that, when necromancers get bored of doing whatever it is they do, they'll create a group of dolls (player characters), have them all wake up at the same place and time and then manipulate things around them, create challenges, watch them struggle, suffer and invariably lose whatever glimmer of hope they manage to scrape by.
Player motivation
Somewhat similar to PSI*RUN, the main driving force for players is to discover the memories of their characters. Who they were and how they came to be undead and whether the memories and personality they possess is their own. This is made difficult because being able to kinda think like a free-willed human in a fucked-up world can make people mad in a variety of ways.
How gory is this shit?
Just take a look at the cover or skim through the free intro comic. The author must've read Lamentations of the Flame Princess and thought to himself "You know what? This needs more body horror. And lolis". The dolls' bodies will very likely suffer from limb loss or worse at some point, while remaining "alive". Nothing that can't be fixed because, you know, zombie cyborgs.
