"This is why we can't have nice things in Battlefailed, someone will just wind up filling it with corpses."One of the more recent Lets Plays of Dwarf Fortress, making the lofty (if rather accurate) claim of being the Boatmurdered of DF2010, Battlefailed has spawned three sequels and a side story.What began as the (seemingly) coincidental combination of a genocidal plot by the Jerk Ass Human-Queen of the Dwarves and the curious gambit of an incredibly ancient body-surfing Sorcerer. Seven dwarves ended up on the hellish coastline separating the Plains of Ooze from the Blueness of Malodors. Halfway through the first year, most of the original settlers and a good chunk of the new arrivals were either dead or dying. Ten blood-soaked years later, the fortress was an Escher-like nightmare of tunnels, shafts and stairwells leading nowhere, under constant assault from goblins, trolls, forgotten beasts and hordes of undead grazing animals. Eventually, parts of the fort started leaking water or magma for no apparent reason, occasionally in places that it should not have been possible for water or magma to be. Extinction-level events that would kill up to half of the population became not only frequent but regular.When Battlefailed fell, there were attempts to reclaim it and continue the awesome. They failed, the fort was flooded beyond belief and deemed unrecoverable. The sequel, FailCannon: Super Happy Fun Beach, picks up where the previous fort leaves off, and has lived up to the Battlefailed name, albeit with a slightly different style at slower a pace. An intricate Meta Plot has formed out of the players' writings and the actions of the dwarves that continues to frame the gameplay.Several months after Failcannon began, Battlefailed was reclaimed, FAILCANNON rigged to work properly, and everything cleaned up.Failcannon fell on the aptly-named Failday, when the Faillever was pulled to unleash an army of ghosts (and water from the sea) on the fortress. Now, Hellcannon has been started as the third fortress in the series. Whether or not it will live up to the reputation of its predecessors remains to be seen, but Hellcannon is already a hideous abomination rife with death and danger, so there's that.And now, the fourth fort has started, Horrorfailed the Battle-Cannon of Hell.You can grab the most current archive here.
