Introduction and story (Taken directly from Fakku):
Abaddon was a very well-received and popular eroge developed by the doujin group Sakuraprin. It's a retro horror RPG that's a huge love letter to Capcom's Famicom game called "Sweet Home". For the unfamiliar, Sweet Home was kind of like prototype Resident Evil featuring a haunted mansion that you explored. The only difference is this game has porn.
But really, this game has a pretty involved story than it might initially let on. The basic synopsis is simple: the protagonist's father, Yamanobe, is a college professor who goes to explore his friend's old abandoned mansion. Yamanobe never returns though, so the protagonist, Homura, heads to the mansion with some friends to search for his father. Obviously there's much more to it than that, but you'll have to play the game to find out!
Gameplay (Taken directly from Fakku):
Gameplay-wise, you choose two characters as your partners at the start of the game. Each character has their own unique strengths/weaknesses. The RPG elements are fairly standard for the genre, including equipment, items, basic stats, leveling, and different types of enemies. There is, however, one exception: the "Fear Factor" system. A "Fear" bar replaces your typical HP bar in this game. You or your party members will go berserk once their Fear Factor bar is completely filled. This berserk effect will wear off after battle, but this causes permanent psychological damage to each character. This permanent psychological damage will affect character interactions and the types of scenes you'll see as well. Party members will permanently die if they go berserk a total of three times.
It also has typical adventure game elements with exploration and searching for items to progress.
Abaddon has a number of different endings and different scenes that are all influenced by the Fear Factor system and choices made throughout the game.
There are tons of h-scenes in the game, and lots of variety in them—this includes boys love (yaoi) and yuri. Basically, if you can imagine a pairing, it probably exists in this game. In addition to all of the above, every uncensored CG has a corresponding uncensored pixel art variant!
